$[\begin{array}{c} 1 & 3 & 2 & - 10 \\ 0 & 1 & 2 & - 3 \end{array}]$

Langkah 1

Perform the row operation $R_{1} = R_{1} - 3 R_{2}$ to make the entry at $1, 2$ a $0$ .

$[\begin{array}{c} 1 - 3 \cdot 0 & 3 - 3 \cdot 1 & 2 - 3 \cdot 2 & - 10 - 3 \cdot - 3 \\ 0 & 1 & 2 & - 3 \end{array}]$

Langkah 2

Sederhanakan $R_{1}$ .

$[\begin{array}{c} 1 & 0 & - 4 & - 1 \\ 0 & 1 & 2 & - 3 \end{array}]$
