First Order Linear Equations: Am I doing it right?

Just seeing if I understand this correctly.

Here is the problem.

$\displaystyle e^x(dy/dx) + (2e^x)y = 1$

I rewrote the problem to this form:

$\displaystyle dy/dx + ((2e^x)/e^x)y = 1/e^x$

then I found $\displaystyle e^(int((2e^x)/e^x)$ and got $\displaystyle e^(2x)$

Then I found the$\displaystyle int(e^(2x) * 1/e^x) $and got$\displaystyle e^x$

So I wrote the general formula as $\displaystyle (e^x + c)/e^(2x)$

At this point I wasn't sure if I was finished. I read a tutorial online that said I take it further to find C but they used an equation that was given at the start. $\displaystyle y(0) = 1$

in which case I would input 0 to get C+1 = 1 so C = 0

But that y(0) = 1 was never given.

So am I finished then? Is the answer just the general formula of$\displaystyle (e^x + c)/e^(2x)$ or is there more yet to do. Or did I just flat out do it wrong? Can someone help me!
