Solve for x : 3x−3=6x+18

1 answer

To solve for x, first we want to simplify the equation by combining like terms:

3x - 3 = 6x + 18

Next, we want to move all the terms involving x to one side of the equation. Let's start by subtracting 3x from both sides:

-3 = 3x + 18

Next, let's subtract 18 from both sides:

-21 = 3x

Now we can solve for x by dividing by 3:

x = -7

Therefore, the solution for x is x = -7.
