algebra

if I was asked to think of a number and multiply it by 2, I could write this algebraically as 2x
Write the following algebraically, using x as your unknown
"I think of a number, take away 1 and multiply the result by 3"
What have you got so far?
Y = x/3 add 1

To solve

3 (Y-1) = x

Break it down into steps.
