distribute the 3 to the terms inside the parentheses.
The equation becomes 3x - 12 = 18.
Next, add 12 to both sides of the equation to isolate the x-term.
3x - 12 + 12 = 18 + 12
Simplifying the left side of the equation gives 3x = 30.
Finally, divide both sides of the equation by 3 to solve for x.
3x/3 = 30/3
This gives the solution x = 10.
