[comp.text.tex] AMS-TeX Puzzle

c3ar@zaphod.uchicago.edu (Walter C3arlip) (09/30/90)

A colleague has given me a TeX problem that I cannot solve.  Within
AMS-TeX, he would like a display with three aligned, tagged equations
preceeded by a left brace encompassing all three equations.  

The \cases command will not work, since ti does not allow labeling on
multiple lines; \align won't work, because it won't permit any character
to preceed the align; \aligned won't work because it won't allow tagging
of multiple lines.

I suggested inserting tags by hand in an \aligned, using \hfill to push
the tag to the right margin (he is using TagsOnRight).  To my surprise
this also does not work (the \hfill is ignored).  

The desired effect is what the following two samples (which don't work)
"should" generate:

$$
\left\{
\align
a &= b\tag1\\
c &= d\tag2\\
e &= f\tag3
\endalign
\right.
$$

$$
\left\{
\aligned
a &= b\hfill(1)\\
c &= d\hfill(2)\\
e &= f\hfill(3)
\endaligned
\right.
$$

Any suggestions/explanations would be appreciated!
Thanks.
