[texhax] \hline in align environment

[Philip TAYLOR (Ret'd)]

I confess I'm unclear as to exactly what you
are trying to accomplish, but if it is similar
to what I think it is, then there is a far
simpler solution that requires no phantoms :
could you please take a look at --

> \documentclass {minimal}
> \usepackage {AMSmath}
> \begin {document}
> 
> \begin {align*}
>       4x+  6y -2z &= -4\\
>        x -y +2z   &=  9\\[-1.4 ex]
>        \multispan 2 {\leaders \hrule \hfil}\\
>        5x + 5y    &= 5\\
>         x + y &= 1
> \end {align*}
> 
> \end {document}

and tell me if it is close to meeting your needs ?
