latex中怎么输入方程组(有左括号,左对齐)\begin{equation}\left\{\begin{aligned}a+b&=2\\a-b&=4\\\end{aligned}\right\end{equation}怎么运算不出来啊?是什么原因啊?应该怎么修改!或者换成什么别的代码?

\end{equation} \begin{align}...\end{align}(\begin{align*}...\end{align*}) 最基本的对齐环境,采用“&”分割各个对齐单元(每行可以使用多个“&”,但每一行的“&”个数要相同,即一一对应),使用“\\”换行。每行公式都有独立编号。相比后面介绍的split以及cases,align的行间距我感觉会更大一些。
若线性方程组\begin{equation}\left\{\begin{aligned} x_{1}+2x_{2}+x_{3}&=1 \\ 2x_{1}+3x_{2}+(\lambda+2)x_{3}&=3 \\ x_{1}+\lambda x_{2}+ 2x_{3}&=1 \\ \end{aligned} \right.\end{equation}无解,则\(\lambda= \)A.1B.2C.3D.4的答案是什么.用刷刷题APP,拍照...
