Answer:

X=5, y=-8

Step-by-step explanation:

-X + y =-13 equation 1

-8x-4y=-8 equation 2

4(-x+y)=4(-13). Multiply equation 1 by 4 to eliminate y

-4x + 4y =-52

———————————-

-4x + 4y =-52 equation 1 after multiplying by 4

-8x-4y=-8. Equation 2

-12x=-60 added 2 equations above

x=5

solve for y

-x+y=-13

-5+y=-13

y=-8
