Answer:
A) x = 6
Step-by-step explanation:
Step 1: Get all x terms to one side, and all constants to the other side
4x - 2x + 6 = x + 12
4x - 2x - x + 6 - 6 = x - x + 12 - 6 (subtract 'x' and '6' from both sides)
4x - 2x + x = 12 - 6 (simplify)
x = 6 (combine like terms, 4x - 2x + x is 'x', 12 - 6 is '6')
