Have you tried cross multiplying? It should be possible to collect like terms for dy/dx and then use subject formula.
Thanks for the reply. Do you mean multiplying out the 4(x−y)3(1−y′) and then collecting the y' terms? I thought about doing that, but is there another way that would be less time consuming in the exam?

Also, just to clarify, multiplying out the above just means getting:
