Thanks Jean,
I tested that and it works, but stuff doesn't line up the way I'd like. What
I'd really like is an \eqnarray* with 4 columns instead of 3, so I could do
something like this:
\begin{eqnarray*}
2x+y&=&z\qquad\qquad &\mbox{this is the explanation}\\
31x+64y&=&71z\qquad\qquad &\mbox{another explanation}\\
\end{eqnarray*}
That would work perfectly, but I get this error if I put in three & symbols on
a line:
! LaTeX Error: Too many columns in eqnarray environment.
If I remove the & before the equal sign, it compiles, with the equal signs
under each other, and the explanations all lined up perfectly, but the right
sides of the equations don't line up, but instead are centered under each
other, which looks confusing to the reader.
I could do it with a separate minipage for all the explations, but that would
require huge amounts of ERT, I would think. It would completely separate the
explanations from the equations they explain. Doing it that way would be very
hard in LyX, be unreadable or confusing in LyX, and probably require lots of
ERT.
So if anyone knows how to get a four column \eqnarray*, please let me know.
