Solution of these 2 differential equations

y'(x)=(2x+3y+1)^2

and

x-y*cos(y/x)+xy'*cos(yx)=0
?

Separately? Or are they coupled?

If separately, then the first one is easily identified as the Riccati equation. The second one I'm not so sure. It looks like there could be a substitution of sorts. Otherwise you'll have to solve numerically.
