Answer 2

well, to get -9 we subtracted 7 and then multiplied by 3, right? we want to go "backwards" on this problem to get the original number

the last thing we did was multiply by 3, so we'll want to divide -9 by 3, then we'll add 7 to get the final answer

Answer 3

okay so then the answer is 4?

Answer 4

yup, good job

Answer 5
