Whakaoti i te 300+80x/x=98/1

$$\frac{ 300+80x }{ x } = \frac{ 98 }{ 1 }$$

Whakaoti mō x

$$x = \frac{50}{3} = 16\frac{2}{3} \approx 16.666666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.

$$300+80x=x\times 98$$

Tangohia te x\times 98 mai i ngā taha e rua.

$$300+80x-x\times 98=0$$

Pahekotia te 80x me -x\times 98, ka -18x.

$$300-18x=0$$

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

$$-18x=-300$$

Whakawehea ngā taha e rua ki te -18.

$$x=\frac{-300}{-18}$$

Whakahekea te hautanga \frac{-300}{-18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -6.

$$x=\frac{50}{3}$$
