How do you do this question.

f(x) = (5x-1)/(2-3x), find f^(-1)(x). The answer is supposed to be (1+2x)/(5+3x).

--------------------------------------

And can you please explain this one to me.

Suppose that xy^(3)+2y^(2)+xy+2x^(3) = 0. Find the general expression for dy/dx. Also, find the value of dy/dx at the point where x = 1.

I have no idea how to differentiate that.

Thanks so much for the help!
