A. -15
B. 15
C. -3
D. 3

1 answer

To solve the equation 6x + 12 = 4x*18, we can start by subtracting 4x from both sides:
6x - 4x + 12 = 18.
This simplifies to 2x + 12 = 18.

Next, subtract 12 from both sides:
2x + 12 - 12 = 18 - 12.
This simplifies to 2x = 6.

Finally, divide both sides by 2 to solve for x:
2x/2 = 6/2.
This simplifies to x = 3.

Therefore, the solution to the equation is x = 3, which corresponds to option D.
