Question

In order to solve the following system of equations by addition, which of the following could you do before adding the equations so that one variable will be eliminated when you add them? - 4x + 3y = - 11; 3x - 2y = 8 . Multiply the top equation by -3 and the bottom equation by 4. B. Multiply the top equation by 3. C. Multiply the top equation by 2 and the bottom equation by 3. . Multiply the bottom equation by 4.

Answer 1

C. Multiply the top equation by 2 and the bottom equation by 3

Explanation:

-4x+3y=-11

3x-2y=8

If you multiply the top equation by 2 and the bottom equation by 3 you get

-8x+6y=-22

9x-6y=24

And you can see once you add these equations together the y variable will be canceled out

Answer 2

- 4x + 3y = - 11

3x - 2y = 8

A. Multiply the top equation by -3 and the bottom equation by 4

B. Multiply the top equation by 3

C. Multiply the top equation by 2 and the bottom equation by 3

D.Multiply the bottom equation by 4
