You can put this solution on YOUR website! First, you need to eliminate one variable or the other; I'm choosing to eliminate x, by multiplying the first statement by 4, and the second statement by 3:
Now, subtract the first statment from the first:
Substitute for y into either equation (I choose the second)
To prove, substitute into both equations:
3(-2) + 2(5) = 16
-6 + 10 = 4
16 = 16.
4(-2) + 3(5) = 7
-8 + 15 = 7
7 = 7.
