The difference of a number, n,and is less than 9

Step-by-step explanation:

First you would have to figure out what the n= so lets say that n=2

Next you would think of a number that is less than 9 (you don't have to put this number I am just to show you). So my number is gonna be 7.  

I chose the number 7 because if you minus n which equals 2 and add 7 it would equal the number 9. If you did 9-2 which is n it would be 7. So you can do multiple number like n=3 and the number less is and see if it works.

I hope this was very helpful to you.
