注意{amsmath}包的引入

1. 不标号方程组 \usepackage{amsmath} $$ \begin{cases} l_{11}y_{1} = 1 \\ l_{21}y_{1} + l_{22}y_{2} = 0 \\ l_{31}y_{1} + l_{32}y_{2} + l_{33}y_{3} = 0 \\ l_{41}y_{1} + l_ {42}y_{2} + l_{43}y_{3} + l_{44}y_{4} = 0 \end{cases} $$

or:

\usepackage{amsmath} \begin{equation*} \begin{cases} l_{11}y_{1} = 1 \\ l_{21}y_{1} + l_{22}y_{2} = 0 \\ l_{31}y_{1} + l_{32}y_{2} + l_{33}y_{3} = 0 \\ l_{41}y_{1} + l_ {42}y_{2} + l_{43}y_{3} + l_{44}y_{4} = 0 \end{cases} \end{equation*}

{ l 11 y 1 = 1 l 21 y 1 + l 22 y 2 = 0 l 31 y 1 + l 32 y 2 + l 33 y 3 = 0 l 41 y 1 + l 42 y 2 + l 43 y 3 + l 44 y 4 = 0 \begin{cases} l_{11}y_{1} = 1 \\ l_{21}y_{1} + l_{22}y_{2} = 0 \\ l_{31}y_{1} + l_{32}y_{2} + l_{33}y_{3} = 0 \\ l_{41}y_{1} + l_ {42}y_{2} + l_{43}y_{3} + l_{44}y_{4} = 0 \end{cases} ⎩⎪⎪⎪⎨⎪⎪⎪⎧l11y1=1l21y1+l22y2=0l31y1+l32y2+l33y3=0l41y1+l42y2+l43y3+l44y4=0

2. 标号方程组 (1)方程组整体标号 \usepackage{amsmath} \begin{equation} \begin{cases} l_{11}y_{1} = 1 \\ l_{21}y_{1} + l_{22}y_{2} = 0 \\ l_{31}y_{1} + l_{32}y_{2} + l_{33}y_{3} = 0 \\ l_{41}y_{1} + l_ {42}y_{2} + l_{43}y_{3} + l_{44}y_{4} = 0 \end{cases} \end{equation}

(2)方程组中的每一行方程都标号 \usepackage{cases} \begin{numcases}{} l_{11}y_{1} = 1 \\ l_{21}y_{1} + l_{22}y_{2} = 0 \\ l_{31}y_{1} + l_{32}y_{2} + l_{33}y_{3} = 0 \\ l_{41}y_{1} + l_ {42}y_{2} + l_{43}y_{3} + l_{44}y_{4} = 0 \end{numcases}
