## Homework Statement

Working together, Bill and Tom painted a fence in 8 hours. Last year,

Tom painted the fence by himself. The year before, Bill painted it by himself,

but took 12 hours less than Tom took. How long did Bill and Tom take, when each was painting alone?

(represent the above with an equation without using rational equations)

## Homework Equations

none

## The Attempt at a Solution

I came up with the following equation.

(b = bill; t = tom)

b + t = 8

b = t - 12

However the above answer is incorrect

Thanks your help is appreciated.
