Equation: 4x + 2(x - 2) = 4x + x - 12
Solve:
4x + 2(x - 2) = 4x + x - 12
4x + (2)(x) + (2)(- 2) = 4x + x + - 12 (Distribute)
4x + 2x + - 4 = 4x + x + - 12
(4x + 2x) + (- 4) = (4x + x) + (- 12)
Combine Like Terms:
6x + - 4 = 5x + - 12
6x - 4 = 5x - 12
Subtract 5x from both sides:
6x - 4 - 5x = 5x - 12 - 5x
x - 4 = - 12
Add 4 to both sides:
x - 4 + 4 = - 12 + 4
x = - 8
Answer: x = - 8
Hope that helps!!!! ( x = - 8, Letter Choice (A).
