y = \frac{{x - 1}}{{x - 2}}

[/tex]

Heres my working for it:

[tex]

\begin{array}{l}

x = \frac{{y - 1}}{{y - 2}} \\

xy - 2x = y - 1 \\

xy - y = 2x - 1 \\

(x - 1)y = 2x - 1 \\

y = \frac{{2x - 1}}{{x - 1}} \\

\end{array}

[/tex]

The answer says something different though.

If anybody could please tell me where I am going wrong, or perhaps if the answer book is wrong, id greatly appreciate it.

Thanks,

Dan.
