Hello! I bought an SAT practice book to get ready for the big test. It is pretty well formated, except it only has the answers/explanations to random questions. I was just hoping that you guys could help me with a question here or there that I didn't know how to solve. Thanks!

Solve for x, where 0<x<pi: 6e^x * tan(x) - 3tan(x) + 8e^x -4 = 0

This is what i did:

factor: 3 tan(x) [2ex - 1] + 4 [2ex - 1] = 0

factor further: .[2ex - 1] [3 tan(x) + 4] = 0

know what? I'm not so familiar with the e's (are they called natural logs).

Thanks, for your help!
