How do you use inverse operations to find out. x/-7 +6 = 3

First you would subtract 6 from both sides.
x/-7 = -3

then you would multiply both sides by -7
x = 21

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
