Kneel and beg for math problems, and ask for math problems for gods

Method 1: Let's set the number of people who go to Li Village as x people, and the people who go to Zhou Village as (60 x) people.

25x＋18(60－x)＝1339 25x＋1080－18x＝1339

7x＝259

x 37 then 60 x 23

37 23 14 (person).

A: There are more people going to Li Village, 14 more than Zhou Village.

Method 2: If there are 60 people in Zhoucun, a total of 18 60 1080 yuan will be sold. The actual receipt was 1,339 yuan, that is, 1,339 1,080,259 yuan more.

Also, the ticket to Li Village is 25 18 7 yuan more than the ticket to Zhou Village. According to the principle of contrast, the column formula is as follows:

1339 60 18) (25 18) 37 (person) 60 37 23 (person).

37 23 14 (person).

A: There are more people going to Li Village, 14 more than Zhou Village.

Solution: There are more people who go to Li Village.

Set the number of people who went to Zhou Village to x, and the number of people who went to Li Village was 60-x.

18x+25*(60-x）=1339

18x+1500-25x=1339

1500-1339=25x-18x

7x=161

x=2360-x=60-23=37

60-x-x=37-23=14

Answer: There are more people at Licun Station. There were 14 more people in Li Village than in Zhou Village.

Solution: Set up x people in Zhou Village, and Y people in Li Village.

x+y=60

18x+25y=1339

Solution: x=23

y=3737-23=14 (person).

A: There are more passengers to Li Village, 14 more people.

Everyone should get 1,500 yuan to sell tickets in Li Village, 1500-1339 = 161, 161 divided by (25-18) = 23, 23 people in Zhou Village, 37 people in Li Village. This is the principle of chickens and rabbits in the same cage, which is much simpler than setting unknowns.

Solution: There are x people in Li Village, and 60-x people in Zhou Village.

25x+18(60-x)=1339

7x=1339-1080x=37

A: There are 37 people in Li Village, 23 people in Zhou Village, and there are 14 more passengers at Li Village Station.

It's detailed enough to give points.

The people of Zhou Village are x, and the people of Li Village are y:

x+y=60

18x+25y=1339

Solve: x=23

y=37 then 23 people in Zhou Village and 37 people in Li Village.

More than 37-23=14 people.

Let X be a native of Zhou Village, and Y is a native of Li Village.

x+y=60

18x+25y=1339

x=23y=37

Li has 14 more people than Zhou.

I'm telling you that it's easiest to set up unknowns, and I hope you'll do it in the future.

There are 23 people in Zhou Village and 37 people in Li Village. It's very simple, make an equation and it comes out.

There's a problem with the subject.,Multiply the two sides of the first formula equal sign by 3 and then compare it with the third formula.,It's obviously not right......

1)3x^2-9x+3=0

3)3x^2-9x+2=0

1、 x=（3±√5）／2

2、 x1=2，x2=3／2

3、 x=（9±√57）／6

It's not too late to hope.

What's going on with this?

distance Hello:

The next day, I read the whole book:

The next day I watched it:

720 7 15 336 (pp.).

After the timber is cut into three sections along the cross-section, the surface area is increased by 4 cross-sectional areas, and the increase is known to be square meters, so the cross-sectional area = square meters).

Original timber volume = cross-sectional area length = cubic meters).

Answer: 6 (2 5-1 3) = 90 tons.

2 5-1 3 is the part that is now more than the original, 6 is the actual amount of the excess, the original amount = the actual excess amount and the percentage of the excess.

Solution: Let the original be x tons, 2 3x+2 5x-x=6

10/15x+6/15-x=6

16/15x-x=6

1/15x=6

x=90 Look at how hard I've worked, give points)

distance Hello:

1: A bag of rice that eats 25% of the total for the first time, eats the remaining 50% the second time, and eats what percent of the total for the second time? What percent of the total is left in this bag of rice?

The second time the total is eaten: (1 25%) 50% The total remaining: 1 25%.

2: There is a red cloth in a box, and a yellow cloth is given to the child, and a red cloth and a yellow cloth are used, so that two-thirds of the red cloth is used, and three-fifths of the yellow cloth is used.

There is a total of cloth: 1 2 3 1 3 5 19 6 The cloth sent away accounts for all the cloth: (1 1) 19 6 12 19

1：；Still is.

2: 12/19.

The area is (3 + 2) 2

The isosceles trapezoidal base angle is 45 degrees from Figure 1. So the top bottom is two times shorter than the bottom bottom.

Figure 2 shows that the parallelogram is twice as high as the trapezoid.

a＋b＝6a－b＝2√2

Did you add the tag to solve A, B, and higher mathematics?

I have mixed feelings.
