我想使用 \mathindent 将所有数学公式从左边距移动 60pt。但是当公式超出文本宽度时，该特定公式将从右向左对齐。
请参阅我的 MWE 如下
\documentclass{book}
\usepackage{amssymb,amsfonts}
\usepackage[fleqn]{amsmath}
\setlength{\mathindent}{60pt}

一个简单的解决方案：在必要时使用fleqn环境（来自nccmath）：
\documentclass{book}
\usepackage{amssymb,amsfonts}
\usepackage[fleqn]{amsmath}
\setlength{\mathindent}{60pt}
\usepackage{nccmath}
\usepackage{showframe}
\renewcommand{\ShowFrameLinethickness}{0.3pt}
