Explanation:

Answer 2

8.5

Explanation:

To work out the original number you would need to work backwards ( do the opposite). First you would do 22-5, this gives us 17. Then you would divide 17 by 2 to work out the original number.

1) Subtract 5 from 22.

`22-5=17`

2) Divide 17 by 2.

`17/2=8.5`

3) The original number was 8.5
