First, we can simplify the equation by removing -3 from both sides:
3x - 3 + 3 = 6x + 18 + 3
3x = 6x + 21
Next, we can subtract 6x from both sides:
3x - 6x = 6x - 6x + 21
-3x = 21
Finally, divide by -3 to solve for x:
x = 21 / -3
x = -7
Therefore, the correct answer is:
A. x = -7
Solve for x: 3x - 3 = 6x + 18
A. x = - 7
B. x = 9
C. x = 2
D. x = - 6
