A. (2,0)

Work Step by Step

We get 2 equations saying y=x-2 and 2x+2y=4. We first substitute the y=x-2 into 2x+2y=4. So we get 2x+2(x-2)=4. Then we factor it to get 2x+2x-4=4. Now we plus 4 on both side to get 4x=8. Then we solve it to get the solution for x which is x=2. Then we plus the x value into the equation y=x-2. We get y=2-2 which gives us the solution for y. Which y=0. Now we get the solution for the problem is (2,0)
