The inverse of function f(x) = (2x - 1)/(x - 8) is written in the form of $f^{-1}(x) = (ax + b)/(c + d)$, where a, b, c, and d are all real numbers.  Find a/c.

I think this problem is stated incorrectly and that is why no one has answered it yet.There is an x missing in the expression for \({f}^{-1}(x)\). It should be\({f}^{-1}(x)=\frac{ax+b}{cx+d}\).
