Answer:
(-1,-8)
Step-by-step explanation:
8x + y=-16
-3x + y=-5
Multiply the second equation by -1
3x - y=5
Add this to the first equation
8x + y=-16
3x - y=5
---------------------
11x = -11
Divide each side by 11
11x/11 = -11/11
x = -1
Now we need to find y
-3x +y = -5
-3(-1) +y = -5
3+y = -5
Subtract 3 from each side
3-3+y = -5-3
y = -8
