    [SOLVED] Simple algebraic equation

    1. The problem statement, all variables and given/known data
    I got stuck on solving an equation on this step...

    2. Relevant equations

    3. The attempt at a solution

    I just don't know how to do ln(6-2e^x)... in general, what's ln(a-b)?

    Thanx in advance.

    There is no form for ln(a-b). Take e to the power of both sides of your equation. You do know a form for e^(a+b), right?
