# writing two line equation in parenthesis in LaTeX

How do I write this in Latex. I don't want the figure. How do I write it in equation form

• Welcome to the site! Have you tried anything? It would be good to see what you've tried! To get started, you might try, for example $\left(\begin{array}{@{}c}line 1\\ line 2\end{array}\right)$ – cmhughes Apr 5 at 8:53

You can do that in several ways. One of the simplest uses the stackengine package:

\documentclass{article}
\usepackage{amsmath}
\usepackage[usestackEOL]{stackengine}

\begin{document}

$\left(\Centerstack{rate of mass\\accumulation}\right) = \left(\Centerstack{rate of \\ mass in}\right)- \left(\Centerstack{rate of \\ mass out}\right)$%

\end{document}


• It does not work shows error – Shafiq Ahmad Apr 5 at 12:40
• Which error do you have? – Bernard Apr 5 at 12:49
• I can't find file listofitemsold.tex'. <to be read again> \relax l.67 {\input listofitemsold.tex\relax\endinput} % Please type another input file name: – Shafiq Ahmad Apr 5 at 12:55
• I want to write it in equation form, Sorry Im new to latex. – Shafiq Ahmad Apr 5 at 12:59
• But can you compile this very code (and only this code)? – Bernard Apr 5 at 12:59

A solution without any package - also works in Plain TeX:

\documentclass[20pt]{extarticle}

\begin{document}

$\pmatrix{\hbox{rate of mass} \cr \hbox{accumulation} } = \pmatrix{\hbox{rate of} \cr \hbox{mass in}} - \pmatrix{\hbox{rate of} \cr \hbox{mass out}}$

\end{document}
