Homework Help: Introductory Question

  1. Sep 26, 2008 #1
    5 years ago, I was one-sixth age of my brother. In three years my age doubled will match my brother's age. How old is my age.

    I tried setting up with 2 variables

    1/6(I-5) = B-5

    2(I+3) = B+3

    and solved for I then i get a fraction.

    is there any better approach to this?

    You posted this in the wrong forum. Regardless, while your second equation is correct, you reversed your B and I in the first.
