[tex] y'= \frac{y}{1+e^x}+e^{-x} [/tex](adsbygoogle = window.adsbygoogle || []).push({});

It's an easy first order linear inhomogenous eq. I solved it by hand with the formula that one can find anywhere AND with Mathematica, but when I take the derivative to check the solution it comes out wrong and it's freaking me out. Can anyone here post just the plain solution?
