When 7 is subtracted from a number four times, the result is 3. What is the number?

Step-by-step explanation:

To answer this problem, work backwards!

The question said that 7 is subtracted from a number 4 times. The opposite of this is to add 7 four times.

7 + 7 + 7 + 7 = 28

The problem also says that the result is 3. That means that after subtracting 7 four times, the remainder is 3. Let's add that remainder to our sum (or the answer to an addition problem.)

28 + 3 = 31

Therefore, the number is 31.

Check your work:

Let's subtract 7 from 31 four times.

31 - 7 = 24

24 - 7 = 17

17 - 7 = 10

10 - 7 = 3

After we subtracted 7 four times, the result was 3. That means our answer is correct!
