Answer:

The first equation can be multiplied by 3 and the second equation by 2.

Step-by-step explanation:

Given

2x+3y=25

-3x + y=22

Required

How to eliminate x

To eliminate x using addition, we have to do the following;

1. Take the coefficient of x in equation 1; Coefficient = 2

2. Take the coefficient of x in equation 2; Coefficient = -3

3. Multiply equation 1 by 3

3(2x + 3y = 25)

6x +9y = 75

4. Multiply equation 2 by 2

2(-3x + y = 22)

-6x + 2y = 44

5. Add both resulting equations

6x +9y = 75  +  -6x + 2y = 44

6x - 6x + 9y + 2y = 75 + 44

11y = 75 + 44

Notice that x has been eliminated;
