To solve for x, we need to isolate the variable on one side of the equation.
First, distribute 3 to each term inside the parentheses:
12x - 36 = 84
Next, add 36 to both sides of the equation to get rid of the constant term:
12x = 120
Finally, divide both sides of the equation by 12 to solve for x:
x = 10
Solve for x. 3(4x−12)=84
