I still believe the table is the easier way. I'm attaching an example. Please, check it.

Hi Jean,
\mbox didn't work at all for me, but your \mbox idea inspired me to find
something that while not pretty, is at least not confusing. It's \makebox.
The following aligns left, equal and right, and approximately (though not
exactly) right aligns the explanations:
\begin{eqnarray*}
2x+y&=&z\qquad\qquad \makebox[2in][r]{this is the explanation}\\
31x+64y&=&71z\qquad\qquad \makebox[2in][r]{another explanation and yet }\\
3x+y&=&z\qquad\qquad \makebox[2in][r]{explanation}\\
x&=&z\qquad\qquad \makebox[2in][r]{exp}\\
\end{eqnarray*}
The following approximately centers the explanations, with the
explanation "column" well to the right of the equations:
\begin{eqnarray*}
2x+y&=&z\qquad\qquad \makebox[2in][c]{this is the explanation}\\
31x+64y&=&71z\qquad\qquad \makebox[2in][c]{another explanation and yet }\\
3x+y&=&z\qquad\qquad \makebox[2in][c]{explanation}\\
x&=&z\qquad\qquad \makebox[2in][c]{exp}\\
\end{eqnarray*}
Either of the preceding is doable with a character style for the
explanation,
which points to a command that puts in \qquad\qquad\makebox[2in][c]{#1},
as
suggested by Richard Heck.
This isn't ideal, but I know I can do it, and if worst comes to worst it's
good enough.
Thanks Jean, Richard and everyone!!!
