  1. Aug 15, 2010 #1
    1. The problem statement, all variables and given/known data

    Ok so I'm trying to simplify this

    (x-5)/(x+1) which is apparently equal to 1 - 6/(x+1) but I don't see how there equal like I don't know what was done to this (x-5)/(x+1) to get that 1 - 6/(x+1). I feel kind of dumb as fel as if I should know this but I can't make sence of it one bit. Thank You for any help you can provide me with.

    2. Relevant equations



    3. The attempt at a solution

    Rewrite (x-5)/(x+1) in terms of y=x+1.
