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?
