$[\begin{array}{c} x & 0.4 & 0.3 \end{array}]$

解题步骤 1

Multiply each element of $R_{1}$ by $\frac{1}{x}$ to make the entry at $1, 1$ a $1$ .

$[\begin{array}{c} \frac{x}{x} & \frac{0.4}{x} & \frac{0.3}{x} \end{array}]$

解题步骤 2

化简 $R_{1}$ 。

$[\begin{array}{c} 1 & \frac{0.4}{x} & \frac{0.3}{x} \end{array}]$
