The problem is $\displaystyle 5\frac{dy}{dx}$ +2x = 3

by re-arranging I get the following

y= $\displaystyle \frac{3}{5} -\frac{2x}{5}$ dx

but need help with finding the general solution

i integrated an came up with.

y = $\displaystyle \frac{3^2}{6} - \frac{2x^2}{6}$ +C

p.s. what is the source code for integral sign?
