    Its telling you to simplify u(x,y) as part of another function h(t). Choosing

    [tex] h(t) = \frac{t}{(1+t^2)^{1/2}} [/tex], then h(u) =

    [tex] h(u) = \frac{x-uy}{1+(x-uy)^2)^{1/2}}[/tex] which is your original function. From there:

    [tex] u(x,y) = h(x-uy), u - h(x-uy) = 0 [/tex], where you can solve the PDE
