Question #2630

I've tried to answer this question about ten times, not joke. I don't seem to understand where I'm going wrong. If you could just explain the method behind it, I'd be glad.
3e^x + 6e^-1 - 11 = 0
Thanks.

Expert's answer

It seems to be exponential equation if the equation is written correctly:

3e^{x} = 11-6/e

e^{x} = (11-6/e)/3

x = ln ((11 - 6/e)/3) ≈ 1.075

3e

e

x = ln ((11 - 6/e)/3) ≈ 1.075
