I've been going through problems in a classic maths for physics book, and am stuck on a question.(adsbygoogle = window.adsbygoogle || []).push({});

I can't find the solution for this equation:

y'=[a/(x+y)]^2

I tried directly integrating it, using iterative techniques, and I know it is not homogeneous so I can't use substitution.
