Answer:

x = -5

y = 3/2

Step-by-step explanation:

x+2y = -2

4x + 2y = -17

_______________

-4(x+2y = -2)

4x+ 2y = -17

_______________

-4x - 8y = 8

4x + 2y = -17

_______________

-6y = -9

y = 3/2

plug this value back into 1 of the 2 equations in the original problem to solve for x

x+2y=-2

x + 2(3/2) = -2

x + 3 = -2

x = -5
