Whakaoti i te x_{1}=-2-2/2*(-frac{1{5})}

$$x _ { 1 } = \frac { - 2 - 2 } { 2 \cdot ( - \frac { 1 } { 5 } ) }$$

Whakaoti mō x_1

$$x_{1}=10$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 2 i te -2, ka -4.

$$x_{1}=\frac{-4}{2\left(-\frac{1}{5}\right)}$$

Tuhia te 2\left(-\frac{1}{5}\right) hei hautanga kotahi.

$$x_{1}=\frac{-4}{\frac{2\left(-1\right)}{5}}$$

Whakareatia te 2 ki te -1, ka -2.

$$x_{1}=\frac{-4}{\frac{-2}{5}}$$

Ka taea te hautanga \frac{-2}{5} te tuhi anō ko -\frac{2}{5} mā te tango i te tohu tōraro.

$$x_{1}=\frac{-4}{-\frac{2}{5}}$$

Whakawehe -4 ki te -\frac{2}{5} mā te whakarea -4 ki te tau huripoki o -\frac{2}{5}.

$$x_{1}=-4\left(-\frac{5}{2}\right)$$

Tuhia te -4\left(-\frac{5}{2}\right) hei hautanga kotahi.

$$x_{1}=\frac{-4\left(-5\right)}{2}$$

Whakareatia te -4 ki te -5, ka 20.

$$x_{1}=\frac{20}{2}$$

Whakawehea te 20 ki te 2, kia riro ko 10.

$$x_{1}=10$$

Tautapa x_1

$$x_{1}≔10$$
