1. The problem statement, all variables and given/known data Simplify (1/3 + 1/3y)/(1/y + 1/3) 2. Relevant equations (1/3 + 1/3y)/(1/y + 1/3) = x In this case I am using x to represent the simplified expression 3. The attempt at a solution (1/3 + 1/3 * 1/y)/(1/y+1/3) = (2/3 * 1/y)/(1/y + 1/3) = (2/3y)/(1/y+1/3) = (2/3y)/(3/3y + y/3y) = 2/3y * 3y/(3+y) = 6y/(9 + 3y^2) I obviously did something wrong but I don't see how. Every step I did correctly.
