I really dont know how to start it . it does not fit the methods I learn in the class.

Try letting .

dy/dx = (y-x-1)+ 1/(x-y+2) is the correct equation. it is the first one.

I try y= x+u, dy/dx= 1+ （du/dx） dy/dx = (u-2)-[1/ (u-2)]. integrating u', I have u= 0.5 u^(2) - 2u- ln(u-2). I dont know how to do next.
