A number is decreased by seven. Then, the new number is multiplied by 3 to get an answer of -9. What is the original number?

    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
