I was asked to show that ∫ (1+e^4x)/〖(4x+e^4x)〗^3 dx= -1/(8(4x+e^3x )^2 )+c (x>0)

And I did.

But the next question goes "hence find, in implicit form, the general solution of the differential equation dy/dx= -(〖4e〗^(-2y) (1+e^4x ))/(4x+e^4x )^3 (x>0)"

I am not sure what to do can I get some help please
