the 1 infront of the parentheses multiples whatever is inside the parentheses. So it simplifies to 4x + 8 + 3x = 36
(the 8 used to be negative)
then you combine the x’s:
7x + 8 = 36
then you do the opposite on the other side:
7x = 36 - 8
then it becomes simplified:
7x = 28
then you divide:
28/7
x = 4
