Question

What should we multiply the top equation by in order for both equations to have like coefficients?

2x-6y=26
-4x+5y=-31

Answer 1

Multiply by 2

Explanation:

If we multiply 2x-6y=26 by 2, we get 4x-12y=52 and the x's cancel out, making it easier to solve for y, using the elimination process.

Hope this makes sense!
