Solving for x

  1. Mar 4, 2009 #1
    1. The problem statement, all variables and given/known data
    How would you solve for x in y = (x+4)/(x+3)

    2. Relevant equations

    3. The attempt at a solution
    y(x+3) = (x+4)

    ...... That is the closest to anything familiar I could come.

    This isn't really a homework question but how would you do this? Is it even possible?

    Wow..... I can't believe that it was a simple 2 steps from there. I just seem to have a problem with solving for x when it is in a numerator and denominator (I had another problem like this and someone else had to figure it out for me)
