Matematica discreta Esempi

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

Passaggio 1

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

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

Passaggio 2

Semplifica $R_{2}$ .

$[\begin{array}{c} 1 & 0 & 2 \\ 0 & 1 & 5 \end{array}]$
