I need neither of the following:

\begin{equation}
\begin{cases} 
ab =st \\ 
a-b =s+t 
\end{cases}
\end{equation}

\begin{equation}
\begin{cases} 
ab &=st \\ 
a-b &=s+t 
\end{cases}
\end{equation}

enter image description here

Instead, I want something like this with bracket on the left:

 ab=st
a-b=s+t

How to achieve this? Thanks.

Inspired by Mico's answer.

\documentclass{article}
\usepackage{amsmath}
\usepackage{mathtools}
\begin{document}
\begin{equation}
\left\{
\begin{array}{@{} r @{{}={}} l}
ab &st\\
a-b &s+t 
\end{array} \right.
\end{equation}
\end{document}

    If you want to emulate cases, add \renewcommand{\arraystretch}{1.2} after \left\{. – egreg May 12 '18 at 6:31
  • if loading mathtools, it's redundant to load amsmath`. – barbara beeton May 13 '18 at 22:05
  • @barbarabeeton Thanks! (I know that but I feel it's "fairer" to load a package that defines the macro I am using.) – user121799 May 13 '18 at 22:10
