[Tex/LaTex] system of equation without the brackets? Possible

bracesbracketsequations

Hi can i make a system of equations like the one below

\[
\systeme{2y+4x=9, 3x-2y=10}
\]

But WITHOUT the bracket (braces) behind the equations?

Best Answer

Use \sysdelim.. to remove the left and right delimiters.

\documentclass[preview,border=12pt,varwidth]{standalone}
\usepackage{systeme,mathtools}

\syscodeextracol{\quad\hfill}{\hfill}
\sysautonum*{(\uppercase\expandafter{\romannumeral*})}
\sysdelim..

\begin{document}
\abovedisplayskip=0pt\relax% don't use this line in your production.
\[
\systeme{
2y+4x=91,
3x-2y=10}
\]
\end{document}

You can use \vphantom to adjust the size so that max is used. The macro below has 4 parameters:

The width of the parbox. If you want to allow for different widths you could adjust this macro to take two paramters, one for each width. This parameter is optional and defaults to 0.425\textwidth.
The brace that you want to use.
The content of the left \parbox
The content of the right \parbox

Here is what it looks like with a curly brace: \RelatedText{\}}{\lipsum[2]}{\lipsum[3]}

enter image description here

\documentclass[12pt]{memoir}
\usepackage{lipsum}

\newcommand{\RelatedText}[4][0.425\textwidth]{%
\begin{math}%
  \left.% 
  \parbox{#1}{#3}\vphantom{\parbox{#1}{#4}}%
  \right#2%
  \parbox{#1}{#4}\vphantom{\parbox{#1}{#3}}%
\end{math}
}%

\begin{document}
    \RelatedText{)}{\lipsum[2]}{\lipsum[3]}% Use a round )

    \RelatedText{\}}{\lipsum[2]}{\lipsum[3]}% Use a curly }

    \RelatedText{]}{\lipsum[2]}{\lipsum[3]}% Use a square ]
\end{document}

[Tex/LaTex] Two double-line equations need double left brackets

I think that some information about the actual expressions might be useful to decide which structure(s) would be best to use; in its present form (using arrays for the two subgroups), one could use a cases environment for the outer brace:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{equation}
\begin{cases}
      \left\{ 
        \begin{array}{lcl}
        1 \\
        2
        \end{array}
      \right. \\
      \left\{      
        \begin{array}{lcl}
        3 \\
        4
        \end{array}
        \right.
\end{cases}
\end{equation}

\end{document}

enter image description here

Here's another option, using a gather environment for the whole structure, and nested arrays:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{gather}
  \left\{
    \begin{array}{@{}l@{}}
      \left\{ 
        \begin{array}{lcl}
        1 \\
        2
        \end{array}
      \right. \\
      \left\{      
        \begin{array}{lcl}
        3 \\
        4
        \end{array}
      \right.
    \end{array}
  \right.
\end{gather}

\end{document}

enter image description here

By the way, your code has some typos like \end{array{lcl}.
