나는 empheq
.
\documentclass{article}
\usepackage{amsmath,empheq}
\usepackage{showframe}% just for the example
\begin{document}
\begin{empheq}[left={a=\empheqlbrace}]{align}
& bbbbbbbbbbb, \\
& ccccccccccc,
\end{empheq}
\end{document}
그러나 행에 번호를 매겨야 하는 경우에는 다음을 추가하는 것이 좋습니다 subequations
.
\documentclass{article}
\usepackage{amsmath,empheq}
