solve for x 3x - 3 = 6x + 18

Answer 1

To solve for x, we need to isolate x on one side of the equation.

3x - 3 = 6x + 18

First, let's simplify the equation by combining like terms:

-3 = 3x + 18

Next, let's move all the x terms to one side by subtracting 3x from both sides:

-3 - 3x = 18

Now, isolate x by subtracting 18 from both sides:

-3 - 3x - 18 = 0
-3x - 21 = 0

Now, divide by -3 on both sides to solve for x:

x = -7

Therefore, the solution is x = -7.
