Hi, I have an equation and I want y be as a fuction, in fact, I 'd like a function in which x is independent variable and y is dependent to x,could you please help me how to do it?

A is a complicated equation but doesn't have "y" in it so it is not important what it is, a and b also have values.

(a*y-x*(a+1))/(x^(2)-b*a^(2)*(y-x)^(2))=A
