8x - 4y = -32
-3x + 4y = 42
(add)
5x = 10
÷ 5
x = 2
(-3 × 2) + 4y = 42
-6 + 4y = 42
+ 6
4y = 48
÷ 4
y = 12
So x = 2 and y = 12, or (2, 12)
I hope this helps!

8x - 4y = -32
-3x + 4y = 42
---------------------add
5x = 10
x = 2
8x - 4y = -32
8(2) - 4y = -32
16 - 4y = -32
-4y = -32 - 16
-4y = -48
y = 12
