Answer:
x=2, y=12
Step-by-step explanation:
8x - 4y = -32
-3x + 4y = 42
add the two equations together to eliminate y
8x - 4y = -32
-3x + 4y = 42
----------------------------
5x = 10
Divide by 5
5x/5 = 10/5
x=2
Now find y
-3x+4y = 42
-3(2) +4y = 42
-6 +4y = 42
Add 6 to each side
-6+6 +4y = 42+6
4y = 48
Divide by 4
4y/4 =48/4
y=12
