That is, an extandable bracket to the left side of the equations.. It seems there isn't any possibility.

https://ask.libreoffice.org/en/question/3044/math-equation-system/?comment=3059#post-id-3059I checked the link; there are some notes at the bottom of the page regarding what I asked but I didn't quite understand how to do it. Anyhow, I found something in the Elements panel name stack which does the job. The final formula is something like left lbrace stack{a # ab # abc} right noneSat, 02 Jun 2012 20:03:27 +0200https://ask.libreoffice.org/en/question/3044/math-equation-system/?comment=3059#post-id-3059Answer by Edmund Laugasson for <p>How do I add an math equation system using Formula feature?

https://ask.libreoffice.org/en/question/3044/math-equation-system/?answer=41564#post-id-41564It seems like it does not exist in LibreOffice Math (yet hopefully). But yes - mentioned workaround works. This moment is not very comfortable to explain to regular user, that she/he have to go into code window and change *rbrace* into *none*. Also the experimental feature, which allows edit formula directly in show area, should be enabled by default. This can be turned on in Tools->Settings->Advanced menu.
For example two formula systems - one without alignment and second one with alignment:
left lbrace { binom { 3 x + y = 4 } { 2 x - y = 1 } } right none
left lbrace alignl { binom { 3 x - 2 y = 4 } { x + y = 3} } right none
This means, that if equations have unequal length, then alignment would be necessary.
The stack could be used if there is more than 2 equations needed to bind into system.Fri, 24 Oct 2014 17:02:53 +0200https://ask.libreoffice.org/en/question/3044/math-equation-system/?answer=41564#post-id-41564
