Answer:
x = -7
y = 2
Step-by-step explanation:
3x + 8y = -5 -----eqn 1
-2x + 2y = 18 ------eqn 2
From eqn 2
-2x + 2y = 18
Divide through by 2
-x + y = 9
y = 9+x -------eqn 3
Insert in eqn 1
3x + 8(9+x) = -5
3x + 72 + 8x = -5
3x + 8x = -5 -72
11x = -77
x = -77/11
x = -7
From eqn 3
y = 9 + (-7)
y = 9 -7
y = 2
