    let us consider e^x = t => st = e^x dx

    It's a simple \(u=e^x-3,\, du=e^xdx\) substitution.\[ \int \frac{e^{2x}}{e^x-3}dx = \int\frac{u+3}{u}du = \int 1 + \frac{3}{u}du \]

    Note: It's not "times" dx. There is no multiplication, there.

    Oh that's true. So which one of the answers is the correct way to solve then? Integration is a real struggle for me

    Well, you are supposed to be learning. A bit of difficulty should not be construed as a bad sign. Put in the time and thought. Looks like wio and DHASHNI already did most of the work for you. You do the rest.
