Whakaoti i te -x/2y=2

$$- \frac{ x }{ 2y } =2$$

Whakaoti mō x

$$x=-4y$$

$$y\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$-x=4y$$

Whakawehea ngā taha e rua ki te -1.

$$\frac{-x}{-1}=\frac{4y}{-1}$$

Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.

$$x=\frac{4y}{-1}$$

Whakawehe 4y ki te -1.

$$x=-4y$$

Whakaoti mō y

$$y=-\frac{x}{4}$$

$$x\neq 0$$

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.

$$-x=4y$$

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

$$4y=-x$$

Whakawehea ngā taha e rua ki te 4.

$$\frac{4y}{4}=-\frac{x}{4}$$

Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.

$$y=-\frac{x}{4}$$

Tē taea kia ōrite te tāupe y ki 0.

$$y=-\frac{x}{4}\text{, }y\neq 0$$
