Answer:

Explanation:

Find an equation to represent x or y

2x + 2y = -22

-2y

2x = -22 - 2y

Divide by 2

x = -11 -y

Plug in the found equation

5 (-11 - y) +6y = - 63

- 55 -5y + 6y = - 63

-55 + y = - 63

+55

y = - 8

Plug in the y to find x

2x + 2(- 8) = - 22

2x - 16 = - 22

+ 16

2x = - 6

Divide by 2

x = - 3
