如果我正确理解了这个问题，您可以使用\leaders 您可以使用\dotfill但使用点，但使用破折号很容易做出类似的命令。

How can I automatically generate the sequences of dashes within the equations so that \\ they line up perfectly left-to-right.


\begin{eq}{124pt}{18pt}
\begin{equation}
l+m=m+l \dashfill \label{eqn:chap_intro_to_num_02}
\end{equation}
\end{eq}

\begin{eq}{106pt}{18pt}
\begin{equation}
(l+m)+n=l+(m+n)\dashfill \label{eqn:chap_intro_to_num_04}
\end{equation}
\end{eq}

\begin{eq}{78pt}{18pt}
\begin{equation}
x+x+x+x+x+x+x+x+x+x=12x\dashfill \label{eqn:chap_intro_to_num_06}
\end{equation}
\end{eq}

\end{document}
