The number A is 920, which is 20 less than the number B, and the sum of the two numbers A and B is w

It is known that A is 920, which is 20 less than B, then B is 940, so the sum of the two is 920 + 940 1860

The solution is as follows:

The sum of the numbers A and B is 1860

Number B: 920 + 20 = 940

The sum of the two numbers of A and B: 920 + 940 = 1860

Number B is 920 + 20 = 940, so the sum of numbers A and B is 920 + 940 = 1860,,, complete.

The number B is 920 + 20 = 940

The sum of the two numbers A and B is 920 + 940 = 1860

If the number A is 920, which is 20 less than the number B, then the number B is:

The sum of the numbers A and B is:

Answer: The sum of the two numbers A and B is 1860.

1860, the number A is 920b, and the number is less than 20, that is to say, the number B is 940, 940 plus 920, that is, 1860

Answer; The sum of the numbers A and B is 1860

B: 920 + 20 = 940

Answer: The sum of the two numbers A and B is 1860.

According to the title, we know that the number B is 940, and the sum of A and B is equal to 1860.

Summary. The sum of the two numbers A and B is 20, the number A is 2 more than the number B, the number A is 11, and the number B is 9. Let the number A be x and the number B be y, then the following system of equations can be obtained from the meaning of the question:

x + y = 20 (the sum of the two numbers A and B is 20) x - y = 2 (the number A is 2 more than the number B) You can use the elimination method to solve this system of equations, add y to the left and right sides of the equation of the second equation respectively, and get: x = y + 2, and then substitute this formula into the first equation to get: y + 2 + y = 20 to get :

2y + 2 = 20 solves: y = 9 Substituting the value of y into x = y + 2 gives : x = 11 Therefore, the number A is 11 and the number B is 9.

The sum of the two numbers A and B is 20, and the number A is 2 more than the number B, what is the number of A? What is the number B?

The sum of the two numbers A and B is 20, the number A is 2 more than the number B, the number A is 11, and the number B is 9. Let the number A be x and the number B be y, then the following system of equations can be obtained from the meaning of the problem: x + y = 20 (the sum of the two numbers A and B is 20) x - y = 2 (the number A is 2 more than the number B) This system of equations can be solved by using the elimination method, and the left and right sides of the equation of the second equation are added to the left and right sides respectively, and the following equations are obtained:

x = y + 2 and then substituting this formula into the first equation gets: y + 2 + y = 20 simplified to get: 2y + 2 = 20 solution:

y = 9 substituting the value of y into x = y + 2 gives : x = 11 Therefore, the number A is 11 and the number B is 9.

The number of A is 2019 more than number B, what is the sum of the two numbers A and B?

Kiss is happy to solve the problem for you: the sum of the two numbers of A and B is 393

Kiss: The solution process is as follows: B number: 201-9 = 192192 + 201 = 393

There are 120 pear trees in the orchard. It is 4 times the size of an apple tree, and there are many trees in total.

Kiss: Analysis: More means that the number B is 9 less than A, so it is: 201-9=192

Kiss: The answer process is as follows: apples: 120 4 = 30 total: 30 + 120 = 150 trees.

Thank. Kiss: Okay

Then the number of bright cavity is 80*(1-20%)=64

The sum of two round laughs: 80 + 64 = 144

Solution: Let the number of B deficits be x, and the equation is listed according to the meaning of the problem.

1+25%)x+x=9 20,,,volt tremor.

x=, spine.

So the number B is.

If the number B is the leakage x, then the number A is (1+25) x.

x+(1+25％)x=9/20

x+(1+1/4)x=9/20

x+5 4x=9 Trace 20

x=9/20÷9/4

x=1 5Answer: The number B is 1 5.

A10B: 9, 20

A (l, 10, 20), B, 24, 20B.

24 20 B 10 B 9 20

44 20 B 9 Grinding and bending 20

44B 9B Alarm Wheel 9 44

A 24 20x9 44 27 110

One is 25, and the other is 5.

It's a matter of harmony. Draw a picture of Qin's grandson, and you can clearly see it. B is one serving, and A is 20 more than one. The sum of the two is 30, then the overlapping part of the two is 10, and the average is 5 for each copy after the average, then B is 5, and A is 5+20=25.

According to the prompt, the following conclusions can be made, 1, the number A is 10, the number B is, if the number A is 5, the number B is 25.

This problem can be solved by a system of equations, A-B = 20, A + B = 30, then A = 25, B = 5

This problem is a matter of harmony and difference, just check the formula yourself, and you can do it.

I don't want to do it anymore.

A-B = 20

A + B = 30

Solve the equation to get A = 25 and B = 5

Add 20 to B and the total becomes: 182 + 20 = 200

At this time, there are as many B as A, then A is: 200 2=100

B is: 180-100=80

The number A is 240, which is 80 more than the number B, and the number B = 240-80 = 160

The sum of the two numbers of A and B = 240 + 160 = 400

According to the title, the calculation process is as follows, first calculate the number of B, B = 240-80 = 160, then the sum of the two = 160 + 240 = 400

A, the result is 400

First of all, the number of B is required to be 240-80, which is equal to 160

Secondly, the sum of the two numbers A and B is 240 + 160 = 400

240+240-80=400

The number A is 240, which is 80 more than the number B, and the sum of the two numbers A and B is 400.
