let n be the number used for the given number puzzle. use algebra to show how the puzzle works.

1. pick a number
2. subtract 9
3. multiply by 6
4. divide by 3
5. add 18
6. subtract twice your original number
You will always get zero


    Here is how to follow the first six steps. Try finishing it yourself.
    Call the number you pick x.
