    Hey I got stuck on this questions and I was wondering if anyone could give me any clues in what I'm doing wrong?
    I have tried to use substitution to integrate but it doesn't seem to work

    The question is find the general solution of this equation:

    dy/dx= (e^x+3)/ (e^x)

    I have a picture of my workings out, the answer at the back of the textbook is y=x-(3e^-x)+c but I can't to get to this
    Thank you!

    (e^x+3)/ (e^x) = 1 + 3e^(-x)

    I didn't see that, but I get it now! Thank you!
