Hi everyone,

I'm having trouble solving this problem. I think substitution is the way to go but I haven't had a lot of luck.

y^2/2+2ye^x+(y+e^x)dy/dx = e^-x

using u=y+e^x

dy/dx=-y^2/2u-2ye^x/u+e^-x

If this is correct so far, can someone help me with the next few steps? I'm pretty lost on this one and I've been working on it for a few days

Thanks!
