Question

A student is trying to solve the system of two equations given below:

Answer 1

Third option

Explanation:

We need to either divide the second equation by 3 or -3 to get y or -y, where we would then subtract or add both equations OR multiply the first equation by 3 or -3 to get 3y or -3y, where we would then subtract or add both equations.

The only option that does this is the third.

Hope this helps!
