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
y=4/9
Substitute 2y into the x
2(2y)+5y=4
4y+5y=4
9y=4
, so most likely A
