Answer:
8.5
Step-by-step 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.
[tex]22-5=17[/tex]
2) Divide 17 by 2.
[tex]17/2=8.5[/tex]
3) The original number was 8.5
