Chickens and rabbits are caged, there are 26 more chickens than rabbits, a total of 274 feet, how ma

Solution: If there are x chickens, then rabbits are (x-26).

4(x-26)+2x=274

4x-104+2x=274

x=63x-26=63-26=37

So there were 63 chickens and 37 rabbits.

Let's say there are x chickens and y rabbits.

Then x-y=26

2x+4y=274

Solve the equation x=63,y=37

Therefore there are 63 chickens and 37 rabbits.

Solution: If there are x chickens, then rabbits are (x-26).

4(x-26)+2x=274

6x=274+104

x=63x-26=37

A: 63 chickens and 37 rabbits.

The simplest way of thinking.

There are 26 more chickens than rabbits.

Chicken-rabbit = 26....1)

There are 274 feet in total.

2 chickens + 4 rabbits = 274....2)

Chicken = 63 Rabbit = 37

4x+2y=274 x+26=y

37 rabbits and 63 chickens.

Let the rabbit be x and the chicken be y

37 rabbits and 63 chickens.

Let the rabbit be x and the chicken be y

4x+2y=274

x+26=y

Rabbits are x, chickens are (26-x).

26-x)-4x=274

Oh my God! Two legs of chicken, four legs of rabbit, slowly count ha!

Solution: There are x chickens and y rabbits.

According to the conditions in the problem, the system of equations can be obtained.

x–y=26，2x+4y=274

x-y=26, x+2y=137

Get: x=63, y=37

There are 63 chickens and 37 rabbits.

This question is calculated as follows:

If there are x chickens, then rabbits have (x 26), and the equation is listed according to the question:

2x＋4(x－26)＝274

2x＋4x－104＝274

6x＝274＋104

6x＝378

x＝63x－26＝63－26＝37

So, there are 63 chickens and 37 rabbits.

Solution: There are x rabbits and y chickens.

A system of equations can be obtained according to the meaning of the question.

y-x=26，2y+4x=274

y-x=26, y+2x=137

Get: x=37, y=63

There are 63 chickens and 37 rabbits.

Solution: Based on known conditions, calculate:

1. Assuming that the rabbit has a, the chicken has 26+a

a+(26+a)×2=274

4a+52+2a=274

6a=274-52

6a=222

a=222÷6

a=37 rabbits: 37 (only).

Chickens: 26 + 37 = 63 (only).

A: There are 63 chickens and 37 rabbits.

Suppose there is a rabbit, and the chickens can be known from the known conditions: a + 26. The equation is as follows:

ax4+(a+26)x2=274

4a+2a+52=274

6a+52=274

6a=222

a=37，a+26=37+26=63

From this, there are 37 rabbits and 63 chickens.

Solution: If there are x chickens, then rabbits have (x-26).

2x+(x-26)×4=274

2x+4x-104=274

6x=274+104

6x=378

x=378÷6

x = 63 rabbit number: 63-26 = 37 (only).

A: There are 63 chickens and 37 rabbits.

A: 63 chickens and 37 rabbits.

There are 63 chickens and 89 rabbits.

Suppose chickens have x and rabbits have y, then we can get, x 26 y, 2x+4y 274, 2x+4(x-26) 274, 6x 378, x 63, y 63+26 89

So there are 63 chickens and 89 rabbits.

274-2x26) (2-x4).

37 (only) 37 ten 26 63 (only).

A: There are 63 chickens and 37 rabbits.

Chicken 2 + Rabbit 4 = 274, 26 more chickens than rabbits, i.e. chicken = rabbit + 26, so (rabbit + 26) 2 + rabbit 4 = 274, rabbit = 37, chicken = 37 + 26 = 63

If there are x rabbits, then the chickens are x+26

4x+2（x+26）=274

4x+2x+52=274

6x=222

x = 37 chickens for 37 + 26 = 63 and rabbits for 37.

If there are x rabbits, then there are (26+x) chickens, then: 4x+(26+x) 2=2744x+52+2x=2746x=222x=37 chickens: 26+37=63 (only); A:

There are 63 chickens and 37 rabbits, or 26 more chickens than rabbits, and the number of chickens is 2 26 = 52 (birds), and the total number of chickens and rabbits is 274 ,..

If there are x chickens, then there are x-26 rabbits.

2x+4(x-26)=244

2x+4x-104=244

6x=348

x=58 (244-58 2) 4=32.

If there are 58 chickens, then there are 32 rabbits.

Friend, set the rabbit to x (of course, the chicken can also qwq) then the chicken x 20 (a rabbit has 4 legs, a chicken has 2 legs) can be listed as 4x 2 (x 20) 262 solution is OK (if the chicken x, then the rabbit paper is x 20).

Solution: If there are x rabbits, then chickens (x+20).

4x+2(x+20)=262

6x=222

x = 37 chickens: 37 + 20 = 57

Rabbits: x only misses fingers, 24 more chickens than tease rabbits, chickens: x+24.

4x+2(x+24)=138

4x+2x+48=138

6x=90x=15

There are 24 more chickens than rabbits, and 15 + 24 = 39 chickens.

Analysis and knowledge of 26 more chickens than rabbits, the number of chickens is 2 26 = 52 (only), and the total number of chickens and rabbits is 274, it includes two parts, one part is the number of 26 chickens more than rabbits, that is, 52, and the other part is the same number of chickens and rabbits in total, that is, 274-52 = 222 (only); And because the sum of the feet of a chicken and a rabbit is (2+4), the number of rabbits is 222 6 = 37 (only), and the number of chickens is 37 + 26 = 63 (only).

Comprehensive column formula: (274-2 26) (2+4)37 (only) 37+26=63 (only).

A: There are 63 chickens and 37 rabbits.

The number of feet of the less 20 rabbits is 20 4 80

At this time, the number of rabbits and chickens is the same, the average is (4+2) 2=3, so the number of chickens and rabbits is 342 (3 2)=57, and finally there are 57 chickens and 37 rabbits.

If there are x chickens, then there are x-20 rabbits.

2x+4(x-20)=262

6x=342x=57

There are 57 chickens and 37 rabbits.

Chickens and rabbits each have x and y.

y-x=-20

2x+4y=262

x= 57y= 37

There were 37 chickens and 57 rabbits.

If there are x chickens, then rabbits have x-20, and chicken feet are: 2x

Rabbit's feet have: 4 (x-20).

So: 2x+4(x-20)=262

Solution: x=57 (only) x-20=37 (only) i.e.: 57 chickens and 37 rabbits.

Solution: If there are x rabbits, then the chickens are x+20.

According to the title:

4x+2（x+20）=262

4x+2x+40=262

6x=222

x=37x+20=57

That is, if there are 57 chickens, there will be 37 rabbits.

It's the New Year, and I came to my grandmother's house. My second aunt's younger brother and I paid a New Year's greeting to my grandmother, so we went out to play together. Grandma's house has a little sister on the other side of the house, and we often play together, and she has a lot of chickens and puppies.

I counted, chickens and puppies have a total of 36 heads, a total of 100 feet, I can't help but think of an ancient Chinese slip: chickens and rabbits in the same cage do not count, 36 cages exposed. Count 50 pairs of feet, how many chickens and rabbits are there?

I thought it was funny, so I gave them this question. Both of them thought about it and couldn't figure it out. Just ask me to answer.

It's ......When I read the Olympiad book that time, I just thought it was fun, so I memorized it, but I didn't read the solution method, and I had no choice.

The little sister called her father, and her father told us: "This one said that there were 36 heads and 100 legs, and asked how many chickens and rabbits there were. Now let's first look at dogs as rabbits, assuming that 36 are all chickens, and there are 72 feet, which is 28 less than the 100 rabbits in the mouth, because each rabbit is assumed to be a chicken, it has 2 feet less, so we should use 28 2 = 14 (only), a total of 14 rabbits.

There are 36-14 = 22 chickens, and if you calculate the equation, rabbits are (50 2-36 2) (4-2) = 14 (chickens), and chickens are 36-14 = 22 (chickens). "Got it! Expand your knowledge to us!

We scrambled to say. "Well, this chicken and rabbit cage is one of the famous mathematical problems in ancient times. In math competitions, chickens and rabbits in the same cage and evolved problems are more common.

Because this is one of the typical application questions. "By the way, we had this problem in our last competition. "We have one too, and we have a lot of them!"

We were talking with great interest.

In the blink of an eye, a morning passed. We're home, and we've learned a lot today. There are so many math problems in life as well.

First subtract the extra 26 rabbits from the 254 feet, so that the remaining number of rabbits and chickens is the same number of feet.

254-4 26 = 150, number of chickens: 150 (4 + 2) = 25 (only).

The number of rabbits: 25 + 26 = 51 (only).

Chickens and rabbits each have Y and W. w = 26 + ten 4w =. 丫=一26+2w=. w = a 26 = 51-26 = 25. A:There are 25 chickens. There are 51 rabbits.

Let the rabbit be x, the chicken is x-26, 4x+2(x-26)=254, x=51, the rabbit is 51, and the chicken is 25.
