Let the number of houses the boys deliver newspaper = x
Matthew delivers 2x newspapers
His brother delivers x newspapers,
Matthew earns per paper = $0.10
Matthew delivers twice a week so he earns =
His brother earns per newspaper = $0.25
So, equation becomes,
So, there are 31 houses where both these boys deliver newspapers.
