Whakaoti i te x=78/y

$$x= \frac{ 78 }{ y }$$

Whakaoti mō y

$$y=\frac{78}{x}$$

$$x\neq 0$$

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 y.

$$xy=78$$

Whakawehea ngā taha e rua ki te x.

$$\frac{xy}{x}=\frac{78}{x}$$

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

$$y=\frac{78}{x}$$

Tē taea kia ōrite te tāupe y ki 0.

$$y=\frac{78}{x}\text{, }y\neq 0$$

Whakaoti mō x

$$x=\frac{78}{y}$$

$$y\neq 0$$
