Predict: I predict that this question is going to be about working backwards to find a given value.
Read: I think of a number, add 15 and then divide by 4. If the result is 5, what was the original number?
BIG Question: What was the original number?
Solution. We have to work backwards in this problem. Firstly, we have to times 5 by 4 which equals 20. Then we subtract 15 to get our answer, 5.
