![我如何使这个等式左对齐?](https://linux22.com/image/354789/%E6%88%91%E5%A6%82%E4%BD%95%E4%BD%BF%E8%BF%99%E4%B8%AA%E7%AD%89%E5%BC%8F%E5%B7%A6%E5%AF%B9%E9%BD%90%EF%BC%9F.png)
我在 LaTeX 中写了一个方程式,它是居中的。我怎样才能将其左对齐,但不丢失分割?(我仍然希望等号一个接一个)。
代码:
\begin{equation*}
\begin{split}
a &=(3+6+9+12+...+147)+1125\\
&=3 \cdot (1+2+3+4+...+49)+1125\\
&=3 \cdot \displaystyle\frac{49 \cdot 50}{2} + 1125=49 \cdot 75 + 1125\\
&=3675 + 1125\\
&=4900\\
&=70^2 \Rightarrow \sqrt{a} = \sqrt{70^2}=70 \end{split}
\end{equation*}
答案1
我觉得没有理由将此显示屏放在左侧。无论如何……
\documentclass{article}
\usepackage{amsmath}
\begin{document}
The following display is left aligned. I don't know why it should be
treated differently from the other displays, but here it is anyhow.
\begin{flushleft}
$\begin{aligned}
a &=(3+6+9+12+\dots+147)+1125\\
&=3 \cdot (1+2+3+4+\dots+49)+1125\\
&=3 \cdot \frac{49 \cdot 50}{2} + 1125=49 \cdot 75 + 1125\\
&=3675 + 1125\\
&=4900\\
&=70^2 \Rightarrow \sqrt{a} = \sqrt{70^2}=70
\end{aligned}$
\end{flushleft}
Note that dots should be specified with \verb|\dots|, not with
three periods and that \verb|\displaystyle| is not needed; there
is \verb|\dfrac|, if needed (not here).
\end{document}
答案2
我不确定这是否正是您想要的,但您可以将\parbox
宽度设置为 0 来实现这一点。

\noindent\parbox{0mm}{
\begin{equation*}
\begin{split}
a &=(3+6+9+12+...+147)+1125\\
&=3 \cdot (1+2+3+4+...+49)+1125\\
&=3 \cdot \displaystyle\frac{49 \cdot 50}{2} + 1125=49 \cdot 75 +
1125\\
&=3675 + 1125\\
&=4900\\
&=70^2 \Rightarrow \sqrt{a} = \sqrt{70^2}=70 \end{split}
\end{equation*}
