Answer:
x=23
Step-by-step explanation:
We simplify the equation to the form, which is simple to understand
(5x+20)=(3x+66)
Remove unnecessary parentheses
5x+20=(3x+66)
Remove unnecessary parentheses
5x+20=3x+66
We move all terms containing x to the left and all other terms to the right.
+5x-3x=+66-20
We simplify left and right side of the equation.
+2x=+46
We divide both sides of the equation by 2 to get x.
x=23
