Differential equation solution basic

  1. Jan 2, 2015 #1
    Ok so I tried to solve the following differential equation for y by every method (variable separable method/making to variable separable method technique/putting y/x=other variable/making homogeneous to solve equation to get y/x ).But I think I can't solve this particular equation by these methods.

    y(1+xy)dx + x(1-xy)dy =0

    change variables
    u=xy
    v=x/y
    or use integrating factor
    1/(xy)^2
