Select all the equations where c=9 is a solution.
Choose 2 answers:
A) 4-c=5
B) 20=14+c
C) 15=c-6
D) c/3=3
E) 36=4c

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!
