Step-by-step explanation:

To solve this, we have to work backwards. If you divide something by 9, and it equals 5, to figure out the number, we need to multiply by 9. 5*9 = 45. If four was taken away, we have to add it to 45, which is 49. If a number * 7 is 49, then we have to divide by 7 to get the answer. 49/7=7
