A student completed the following problem. Justify each step: 8x + (14 + x) = 59 8x + (x + 14) = 59 (8x + x) + 14 = 59 9x + 14 = 59 9x + 14 - 14 = 59 - 14 9x = 45 x = 5

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
