For #6
x + y = -10
x - y = 2
First solve for y in one of the equations
x - y = 2
-y = 2 - x
y = -2 + x
y = x - 2
Now substitute into one of the equations and solve for x
x + y = -10
x + x - 2 = -10
2x - 2 = -10
2x = -8
x = -4
Replace the letters with their value:
4^3 = 4 x 4 x 4 = 16 x 4 = 64
The answer is 64
