Question

Which of these strategies would eliminate a variable in the system of equations? 5x + 3y = 9

4x - 3y = 9 Choose all answers that apply: (Choice A) A Subtract the top equation from the bottom equation. (Choice B) B Add the equations. (Choice C) C Subtract the bottom equation from the top equation.

Answer 1

(Choice B) Add the equations

Explanation:

The equations that were given are:

`5x + 3y = 9 \\ 4x - 3y = 9`

If we add the equequatiothen the y variable would be eliminated:

`+3y + (-3y) = 0`
