$d/dx((x+1)/y) = ( y-(x+1) dy/dx)/y^2$

$d/dx((x+1)/y) = ((1)y-(x+1) dy/dx)/y^2$

There's not much more we can do without the rest of the equation relating $x$ and $y$ .

We could rewrite a bit, to get:

$= ( y-(x+1) dy/dx)/y^2$

or

$= 1/y - (x+1)/y^2 dy/dx$

What is the derivative of (x + 1)/y(x + 1)/y?
