I have already asked this question: Define an environment similar to align such that it can be used in tabularx or tabular.

Zarko's answer to that question (https://tex.stackexchange.com/a/693393/277990) includes an Addendum whose code gives exactly the output I want for situations in which there is only one group of successive statements whose '=' symbols are horizontally aligned.

I would like to allow for situations in which there is more than one such group. Please see my remarks in the following code:

\documentclass{article}
\usepackage{tabularx}

\begin{document}


% The code given in the Addendum to Zarko's answer:


\begin{tabularx}{250pt}{r l @{;} >{$\raggedright}X<{$} l}


    

  1. & \multicolumn{2}{l}{Math}
             & Words \
    2. 

  2. & m & = 9/3  & Words \
    3. 

  3. &   & = 3    & Words \
    4. 



\end{tabularx}


\vspace{1cm}


The above code is succcessful.
However, it cannot cope with situations in which
there are two or more different groups of successive statements
requiring separate horizontal alignments of = symbols.
For example, look what happens to the output if we keep going
(e.g. if we add lines 4 and 5 to the above):


\vspace{1cm}


\begin{tabularx}{250pt}{r l @{;} >{$\raggedright}X<{$} l}


    

  1. & \multicolumn{2}{l}{Math}
             & Words \
    2. 

  2. & m & = 9/3  & Words \
    3. 

  3. &   & = 3    & Words \
    4. 

  4. & 34x+2 & = 30/2 & Words \
    5. 

  5. & & = 15 & Words \
    6. 



\end{tabularx}


\vspace{1cm}


We see that the horizontal alignment of all four =' symbols is determined by the=' symbol in line 4,
whereas what we want is for the =' symbol in line 3 to be aligned with the=' symbol in line 2
and for the =' symbol in line 5 to be aligned with the=' symbol in line 4.
In other words, we want to eliminate
the space between m' and= 9/3',
and then align the =' symbol in line 3 directly below the=' symbol in line 2.

The second column should be right aligned (towards the =) and math so one of these:

\usepackage{tabularx}
