Understanding e in Algebraic Equations

[939]

Homework Statement

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.

Homework Equations

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

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)

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

Thanks for the help, got it :-)
