    Integration Help (Introductory Calculus)

    Hello all,
    I'm in my first-year at a college.
    I have a mid-term coming up and there's so much to cover.
    I've been weak at math every since grade 12.
    My question:

    integrate (5e^2x/ 7e^2x + 4) dx
    So far I've got

    1. I let u=2x
    du = 2 dx
    du/2 = dx

    2. 1/2 integral (5e^u/7e^u+4) du

    I have no idea how to proceed from here.
    Please help me solving this problem.
    Thanks

    Your integral is \int \frac{5e^{2x}}{7e^{2x+4}}~dx ??

    click on the integral sign in my post, it will show you

    \int \frac{5e^{2x}}{7e^{2x+4}}~dx = \frac{5}{7}\int e^{2x-(2x+4)}~dx
