Solve differential equation solution?

Question

I want to solve for $Y(x)$:

$$ Y(x) = A - Bx + C\ln(A/Y(x)) $$

where $A$, $B$, and $C$ are defined.

Not sure how to go about this. I'm tempted to treat $x$ and $Y(x)$ independently and solve them as roots, but I don't think that would be okay.

Answer 1

As told by Oleksandr R., the result is expressed in terms of Lambert's W function. The result is
y = c W(z) where z = a Exp[(a - b x) / c] / c.
