(9-x)/2 = 2x - 8
(9-x)/2 = 2x - 8 Firstly, we want to multiply both sides by two to get rid of the fraction:9-x = 2(2x - 8)Open up the brackets:9 - x = 4x - 16Finally, we want to get the x's on one side and the numbers on the other. So we collect like terms, by adding 16 to both sides and adding x to both sides25 = 5xDivide both sides by 5 to find x:x = 5
