Answer 1

To solve the equation 6x + 12 = 4x - 18, we need to isolate the variable x.

First, we can subtract 4x from both sides of the equation:
6x + 12 - 4x = 4x - 18 - 4x
2x + 12 = -18

Next, we can subtract 12 from both sides of the equation:
2x + 12 - 12 = -18 - 12
2x = -30

Finally, we can divide both sides of the equation by 2 to solve for x:
2x/2 = -30/2
x = -15

Therefore, the solution to the equation is x = -15.
