I believe the answer is (a+c, b) but I'd double check to make sure.
If you put 0 in the place of x or y, which every one you choose, it will cancel it or and you can just divide the number next to it by the answer (-20, 20). Take it one step at a time, don't try to do both at the same time.
I got yah! Do you want a direct answer or show work?
