How to write equation where all equation are in only opening curly bracket and there is no closing curly bracket and with equation number

Question

This looks a lot like a cases environment (amsmath package). — John Kormylo, Jun 05 '23 at 12:00
Mico's solution below is how I would do it, but your displayed example shows that the terms on the left of the equals sign to be left aligned. If you use aligned you will get a result having them right alighted. If that's an issue, you will want to look at the alignedat environment. — Willie Wong, Jun 05 '23 at 19:00
I would consider to put the brace on the right side. That makes more sense when it comes to the numbering, if on the right side. — mickep, Jun 05 '23 at 20:45

I suggest you embed a

\left\{ \begin{aligned} ... \end{aligned} \right.

construct in an ordinary equation environment.

\documentclass{article} % or some other suitable document class
\usepackage{amsmath} % for 'aligned' environment
\begin{document}
\begin{equation}
\left{
\begin{aligned}
a &= b+c \
d &= e+f \
g &= h+i \
j &= k+l
\end{aligned}
\right.
\end{equation}
\end{document}
