To solve for x in the equation 6x + 12 = 4x - 18, we need to isolate the variable x on one side of the equation.
First, we can combine like terms by subtracting 4x from both sides:
6x - 4x + 12 = 4x - 4x - 18
This simplifies to:
2x + 12 = -18
Next, we can subtract 12 from both sides:
2x + 12 - 12 = -18 - 12
This simplifies to:
2x = -30
Finally, we can divide both sides by 2 to solve for x:
2x/2 = -30/2
x = -15
Therefore, the solution to the equation is x = -15.
Solve the following equation: 6x + 12 = 4x - 18
