Whakaoti i te x*088=300-x*105

$$x \times 088=300-x \times 105$$

Whakaoti mō x

$$x = \frac{20}{7} = 2\frac{6}{7} \approx 2.857142857$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0 ki te 88, ka 0.

$$x\times 0=300-x\times 105$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0=300-x\times 105$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$300-x\times 105=0$$

Whakareatia te -1 ki te 105, ka -105.

$$300-105x=0$$

Tangohia te 300 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-105x=-300$$

Whakawehea ngā taha e rua ki te -105.

$$x=\frac{-300}{-105}$$

Whakahekea te hautanga \frac{-300}{-105} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -15.

$$x=\frac{20}{7}$$
