Gopal says that the sum of a number and 8, multiplied by 3/4, is equal to -12. which equations can be used to find gopal's number?

choose all that apply.
a: 3/4(x+8)= -12
b: 3/4x+6=-12
c: x+6=-12
d: 3/4x+8+-12

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!
