Answer:
x=-3, y=1. (-3, 1).
Step-by-step explanation:
-x+5y=8
3x+7y=-2
----------------
3(-x+5y)=3(8)
3x+7y=-2
--------------------
-3x+15y=24
3x+7y=-2
------------------
22y=22
y=22/22
y=1
-x+5(1)=8
-x+5=8
-x=8-5
-x=3
x=-3
Use the proportion 8/64 = 12/y. Cross multiply to get 8y = 768. Divide both sides by 8 to get y=96
