Equation number to left side of the equation

[Xew]

Hi all, i wanted to do the following with (6) in the same line as the
rest.
How on earth is that done?

\setcounter{tmp1}{6}
\begin{list}{(\arabic{tmp1}) }
\item \begin{eqnarray*}
\rho r(S \backslash A^{\star}) & = & |S| - |A^{\star}| - \rho ^{\star}
S + \rho ^{\star} (A^{\star})\\
& = & |S| - \rho ^{\star} S = \rho S.
\end{eqnarray*}
\end{list}

Btw, im a complete noob in latex so a ready text to copy/paste is the
only way you can help me :/

Thx a lot in advance!!!

if you don't want to hack latex, I think it's easier to just use
amsmath package
and it has option of placing the tag on the left or right, ------- and
by default I think it's on left ?????

a good place to look is amsmath.dtx on your machine,
and "a short introduction to ams math" (sorry not exact :( )

If you don't insist on using the list environment, you might want to
try this:

\usepackage[leqno]{amsmath}

\begin{align}
\rho r(S \backslash A^{\star}) &= |S| - |A^{\star}| - \rho ^{\star}
S + \rho ^{\star} (A^{\star})\tag{6}\\
&= |S| - \rho ^{\star} S = \rho S.\notag
\end{align}
