Answer: x = 2, y = -4

<u>Step-by-step explanation:</u>

4x + y = 4 --> y = 4 - 4x

Substitute "y" with 4 - 4x into the other equation and solve for "x":

x + y = -2

x + (4 - 4x) = -2

4 - 3x = -2

- 3x = -6

x = 2

Substitute "x" with 2 into one of the original equations to solve for "y":

x + y = -2

(2) + y = -2

y = -4
