Step-by-step explanation:
Because each equation is equal to y, you can plug the y equal to each other. Because one y is equal to - 2x-2 and the other is 7x-20, you can set them equal to each other. So you should have
-2x - 2 = 7x - 20
The next step is to solve for x, which mean that x is 2, then plug 2 into one of the original equations (it doesn't matter which one) and solve for y, and when you do that, you will get - 6
