To do this problem, first u combine like terms which in this case would be 5x+3x which is 8x and then that leaves 8x-4=36. Next get rid of the 4 by adding it to both sides, you’re left with 8x=40. Then divide both sides by 8, and that cancels the 8 on the left leaving you with x=5 because 40/8=5. So your answer is A.
