    1. The problem statement, all variables and given/known data

    I am confused because of the e, I don't know how to do algebra with them. I need to solve it and set it to 0 for an integration problem.

    2. Relevant equations

    Solve: 120.3 - e^(.15x) = e^(.15x)

    3. The attempt at a solution

    = 120.3 - e^(.15x) - e^(.15x)

    I can set it to zero by trial and error, but is this part ^ at least correct?

    Add e^.15x to both sides... Gives you 2e^.15x... Divide by 2... Do you know how to solve for e after? (you should)
