Help solve ODEs

I have three differential equations I need to solve, but I've ran into difficulties trying to.

Here they are:
[math] y^{2}lny = y'^{2}+xyy' [/math]
[math] x^{5}yy'+y^{4}=-x^{8} [/math]
[math] y'=e^{\frac{(x+y}{2x-y+1}} +\frac{3y-1}{3x+1} [/math]

If anyone can help with a solution or has any ideas, you're welcome.
