someone please enlighten me on each step taken (as well as integrating both sides of the separable equation involving z and x) in solving the following equation:

(x^2)y'=7(y^2)-2xy

using the subsitution z=(y/x)

i know what has to be done, but im having troubles simplifying into a regular funtion y(x)...

this can be done using bernouilli's method but wanna get the same using the homogeneous substituion method

thanks
