The problem posted (implicitly) is

dy/dx = x+ (1/xy) which is not easily separable.

I assume you wished to post:

dy/dx = (x+1)/xy

which can be separated as:

ydy = (x+1)dx/x = (1+1/x)dx

which can be easily integrated on both sides. The constant of integration can be obtained by substitution of the initial condition y(1)=-4.
