both equation are homogeneous. You can use either of the following substitution:

dy = v dx + x dv

dx = v dy + y dv

The result would be separable equation which you can easily solve. And don't forget to revert back to original variables of x and y then apply boundary conditions as necessary.

thank you po. ☺
