Whakaoti i te 13x/2y=42

$$\frac { 13 x } { 2 y } = 42$$

Whakaoti mō x

$$x=\frac{84y}{13}$$

$$y\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 2y.

$$13x=84y$$

Whakawehea ngā taha e rua ki te 13.

$$\frac{13x}{13}=\frac{84y}{13}$$

Mā te whakawehe ki te 13 ka wetekia te whakareanga ki te 13.

$$x=\frac{84y}{13}$$

Whakaoti mō y

$$y=\frac{13x}{84}$$

$$x\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe y ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 2y.

$$13x=84y$$

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

$$84y=13x$$

Whakawehea ngā taha e rua ki te 84.

$$\frac{84y}{84}=\frac{13x}{84}$$

Mā te whakawehe ki te 84 ka wetekia te whakareanga ki te 84.

$$y=\frac{13x}{84}$$

Tē taea kia ōrite te tāupe y ki 0.

$$y=\frac{13x}{84}\text{, }y\neq 0$$
