1 answer

To solve the equation 3x-3=-18, we need to isolate x on one side of the equation.

We can start by adding 3 to both sides of the equation:

3x - 3 + 3 = -18 + 3

Simplifying:

3x = -15

Finally, we can isolate x by dividing both sides by 3:

3x/3 = -15/3

Simplifying:

x = -5

Therefore, the solution to the equation 3x-3=-18 is x=-5.
