Set: There are x chickens and y rabbits.
According to the title, x=3y+6......(1)
2x+24=8y……(2)
Substituting (1) into (2) yields 2 (3y + 6) + 24 = 8y6y + 36 = 8y
y=18……(3)
Substituting (3) into (1) gives x=60
A: There are 60 chickens and 18 rabbits.
-
Suppose there are x rabbits, then there are 3x+6 chickens, and the equation is 2(3x+6) 4x-24, and the solution is x 6, so there are 6 rabbits and 24 chickens.
-
Assuming that there are 6 fewer chickens, which is 3 times that of rabbits, the chicken feet are 2 times less than the rabbit's feet (24 + 2 6) = 36.
Rabbits: 36 (4 2-2 3) = 18 rabbits.
Chickens: 18 3 + 6 = 60 chickens.
-
If there are x rabbits, then the chickens are 3x+6.
3x+6)×2=4x×2-24
6x-8x=-12-24
x=18 (rabbits).
3x+6=60 (chickens).
-
Solution: There are rabbits x rabbits.
As can be seen from the inscription, the number of chickens is 3x+6, and the equation can be listed according to the inscription as, 4x 2-24 (3x+6) 2
Simplification: 2x 36, solution: x 18, then the number of chickens:
3 18 + 6 60 (only),A: There are chickens60 pcs, rabbit18 pcs
-
There are x rabbits.
2(3x+6)=2(4x)-24
6x+12=8x-24
8x-6x=12+24
x=36÷2
x=18. : There are chickens
60 pcs

Every rabbit's foot.
It's twice as much as chickens.
Well, since chicken feet are 2 times larger than rabbit feet.
This means that chickens are 4 times larger than rabbits.
There are 100 chickens and rabbits.
So there are 80 chickens and 20 rabbits.
-
There are x chickens.
4×(100-x)×2=2x
400-4x=x
5x=400
x=400÷5
x=80.
There are rabbits: 100-80 = 20.
-
Solution: There are x chickens and y rabbits.
x+y=100
2x=8y gives x=80 and y=20
A: There are 80 chickens and 20 rabbits.
-
Set the rabbit has x no file, and the chicken has x+27, according to the title:
2(x+27)=2×4x
x+27=4x
3x=27
x=9So, there are 36 chickens and 9 rabbits.
-
Chicken feet are 2 times the number of rabbit feet, and the number of chickens is 4 times that of rabbits.
Chickens 27 3 4 = 36, rabbits 36 4 = 9.
-
There are 36 chickens and 9 rabbits.
Let the rabbit have x, and the chicken destroys Min Song and has Y, and lists the binary equations Namin:
y=x+27;2y=4x·2
Solving the system of equations yields x=9;y=36
So there are 36 chickens and 9 rabbits.
-
Suppose there are x rabbits such as Yanliang and x+27 chickens. According to the meaning of the question, there are 2(x+27)=2 4x==>x+27=4x=>3x=27==>x=9, so there are 36 chickens and 9 rabbits.
-
Solution: Set the rabbit has x ascending molds, and the chickens have (x 27) noisy and slow.
2×(x+27)=2×4x
2x+54=8x
8x a 2x 54
6x=54x=54÷6
x 927 9 36 pcs.
Answer: There are 36 chickens and 9 rabbits.
-
Suppose there are x rabbits and x-27 chickens. The meaning of the root difference liquid problem is 2(x-27)=2 4x==x+27=4x==3x=27==x,9, so there are 36 chickens and 9 rabbits.
-
This problem can be solved using a one-dimensional equation.
If the number of rabbits is x, the number of chickens is 3x 6
Column equations. 4x+2(3x-6)=108
Solution: 4x 6x-12 108
10x=120
x 12 (pcs).
3x 6 3 12-6 30 (only).
A: There are 30 chickens and 12 rabbits.
-
If there are x rabbits, then the chickens are 3x-6
According to the question, the equation is 4x+2*(3x-6) 1084x+6x-12 108
10x=120
x 12 rabbits have 3*12-6 30
A: There are 12 chickens and 30 rabbits.
-
Suppose there are x rabbits and chickens have 3x-6, and there are 4x+2 (3x-6)=108 legs, and the solution is x=(108+12) 10=12, so there are 12 rabbits and 3 12-6=30 chickens.
-
This is the problem of chickens and rabbits in the same cage, the feet of chickens and rabbits are different, chickens have two feet, rabbits have 4, feet If you assume that chickens have x rabbits have y, then you can list the equation 2x+4y=108
Chickens are three times less than rabbits, and you can also list the equations, x=3 y-6, two unknowns, and two equations can be solved.
-
Set: There are x chickens and y rabbits.
x=3y+6
2x=8y-24
Solution: y=18 (only), x=60 (only).
There are 60 chickens and 18 rabbits.
-
If there are x rabbits, then there are 3x+6 chickens.
2(3x+6)+24=8x
If the solution is x=18, then 3x+6=60
That is, there are 18 rabbits and 60 chickens.

Summary. The chicken feet are ten times less than the rabbit's feet, and the rabbit's feet are twice the chicken feet, so the rabbit head is four times more than the chicken head, and the chicken has ten legs less than the rabbit, which means that the rabbit head is 4 times less than the chicken head and 5 less.
There are a total of 45 chicken and rabbit feet, 10 chicken feet are less than twice the rabbit feet, and there are many chickens and rabbits.
Don't list equations.
Elementary school topics. Okay pro, just can't you set x?
Yes. Can't we children understand this and haven't learned this?
I can't talk about xy in elementary school, and I can also write equations, but I haven't learned equations in elementary school.
Chicken feet are 2 times less than rabbit feet, rabbit feet are 2 times the chicken feet, so the rabbit head is four times more than the chicken head, and the chicken is less than the rabbit with ten legs, which is equivalent to the rabbit head is 4 times less than the chicken head and 5 spring thoughts.
Can you list the solution to the trouble, so I can't explain it to the child.
Hello, dear, is in a column for you.

Answer. Answer] Solution: If the number of exemptions increases by 6 and the number of chickens decreases by 6, then there are x chickens and 3x rabbits, which is derived from the question
2x+3x×4=128+6×2
2x+12x=140
14x=140
x = 10 chickens in a cage: 10 + 6 = 16 rabbits in a cage: 3 10-6 = 24 (a rabbit).
Answer: There are 24 rabbits in the cage and 16 locust tracks.

There are a total of 90 chickens and rabbits, the chicken feet are twice the rabbit's feet, there are (72) chickens, and the rabbits have (18) rabbits, 2*4*90 hail high (2+4*2).
72 (only) 18 (only).
-
72 chickens and 18 rabbits;
Assuming that the chicken has a late knowledge and a rabbit has a rabbit, according to the condition of staring at the late eye, you can list the formula of the party
a+b=90
2a=2x4b
From the above equation, it can be calculated that there are 72 chickens and 18 rabbits.
-
Chicken feet are twice as large as rabbit feet, so you know that chickens are 4 times that of rabbits.
Rabbits: 18.
Chicken: 72 are jealous.

Neyama Mori accompanies the relationship given funny, we can divide it into three.
Then 90 3 = 30 spring hands, then the chicken feet are a total of 60.
60 2 = 30, so there are 30 chickens.

Hello, apple triploid is to take out his quadruple chromosome and cross it with diploid, and then, the resulting seedling will plant it to be a triple g apple.
I'll offer a clever approach here:
If you are lucky enough to see an unusual situation: all the chickens in the cage are standing on one foot, and all the rabbits are standing on two feet. At this time, the foot touching the ground is only half of the 200 feet, that is, 100. >>>More
It's easy for you. Triple overtime pay on holidays definitely does not include the day's salary! Suppose your daily salary is 50 yuan according to the base number, if you work overtime on a statutory holiday, your overtime pay on that day is 50 * 3 = 150 yuan, see clearly, this 150 yuan is just your extra overtime pay on this day! >>>More
Suppose all 100 chickens are chickens, then the total number of feet is 2 100 = 200 (chickens) The number of rabbit feet is 0, and there are 200 more chicken feet than rabbit feet, when in fact there are 16 fewer chicken feet than rabbit feet. Therefore, the difference between chicken feet and rabbit feet is more than known (200 + 16) = 216 (only), because the rabbit in it is replaced by a chicken. For each rabbit that is replaced with a chicken, the number of chickens will increase by 2 and the number of rabbit feet will decrease by 4. >>>More
Did the landlord read some posts saying that Ken Gene developed biochemical chickens, and there were several chicken wings on a chicken without hair, and they were raised with chemical raw materials, isn't it. Don't worry too much, or worry about too much, and there are too few delicatessens outside? Do you sell less duck necks? >>>More
