Creating the algebraic expression

[JayCee]

I have a problem that I'm having trouble with by trying to figure out how to rewrite it in the algebraic formula. I can solve the problem and come up with the right answer, just rewriting it in the proper algebraic way is where I can't solve. This is suppose to be a math trick problem of some sort, so every answer is different based upon the number you choose.


The problem is:

a. Think of a number "x"
b. Double it
c. Subtract 5
d. Multiply by 3
e. Add 9
f. Divide by 6
g. Add 1
h. What is the result (simplify the expression)?

Thanks everyone for the help, I greatly appreciate it.

Can't see why you'd want an algebraic expression for that, but here goes:

[3(2x - 5) + 9] / 6 + 1

Now if you simplify that, you'll end up with only x:

(6x - 15 + 9) / 6 + 1
(6x - 6) / 6 + 1
6(x - 1) / 6 + 1
x - 1 + 1
x

Yeah I know me either, it was a problem from my teacher. I guess he just wants to see if we can put it in a algebraic expression afterwards.. Thanks alot for the help and formula of it.
