Evaluate the expression for x = 2 and y = 4 . (x ^ 5 * y ^ 7) / (x ^ 2 * y ^ 5) only numbers

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!
