Answer:
-4
Explanation:
Simplifying
8(x + 12) = 64
Reorder the terms:
8(12 + x) = 64 (12 * 8 + x * 8) = 64 (96 + 8x) = 64
Solving
96 + 8x = 64
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-96' to each side of the equation.
96 + -96 + 8x = 64 + -96
Combine like terms: 96 + -96 = 0
0 + 8x = 64 + -96
8x = 64 + -96
Combine like terms:
64 + -96 = -32
8x = -32
Divide each side by '8'.
x = -4
Simplifying
x = -4
