    integral of (2x-x)/x

    I need it for a differential equation, but I ended up getting really big coefficients and this homework is due in an hour... I'll work on it myself later, I would just really appreciate a quick answer to this integral, please!

    \int \frac{2x-x}{x} \ dx=\int \frac{x}{x} \ dx

    =\int dx

    =x+C
