Answer 7

If you solve each of those equations for y, then you can set them equal to each other and solve for x. Then you can fill what you get for x back into one of the equations to solve it for y. That's one of several ways to go about this. One of the easier, I think.

Answer 8

yeah but how i can solve for y first?
