Is it possible to make displayed equations aligned with left edge?

#1

Display mode math is in the middle of the page. Can I make it start on the left side where the text starts and leave the numbering on the right side as it is now?

I used these for a while and they worked (I forgot how well). They are respectively an unnumbered left-aligned display equation and an aligned display equation with the place for a label

<assign|equation-left*|<\macro|body>
  <with|mode|math|math-display|true|par-ver-sep|<eqn-ver-sep>|par-mode|left|<no-page-break*><vspace*|<eqn-short-above>><no-indent><vspace|<eqn-short-below>><no-indent*><arg|body><htab|0fn>>
</macro>>

<assign|equation-left-lab|<\macro|body|lab>
  <\surround|<set-binding|<arg|lab>>|<space|5mm><with|mode|text|font-shape|right|(<arg|lab>)>>
    <\equation-left*>
      <arg|body>
    </equation-left*>
  </surround>
</macro>>

I adapted the macro in https://lists.texmacs.org/wws/arc/texmacs-users/2005-02/msg00107.html for my macros.
I think the equation can be automatically numbered in the same way a centered display equation is:

<assign|equation|<\macro|body>
  <\surround|<next-equation>|>
    <\equation-lab>
      <arg|body>
    </equation-lab|<the-equation>>
  </surround>
</macro>>

but I did not test it.
