Whakaoti i te -y=4-3xy=

$$-y=4-3xy=$$

Whakaoti mō x

$$x=\frac{1}{3}+\frac{4}{3y}$$

$$y\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$4-3xy=-y$$

Tangohia te 4 mai i ngā taha e rua.

$$-3xy=-y-4$$

He hanga arowhānui tō te whārite.

$$\left(-3y\right)x=-y-4$$

Whakawehea ngā taha e rua ki te -3y.

$$\frac{\left(-3y\right)x}{-3y}=\frac{-y-4}{-3y}$$

Mā te whakawehe ki te -3y ka wetekia te whakareanga ki te -3y.

$$x=\frac{-y-4}{-3y}$$

Whakawehe -y-4 ki te -3y.

$$x=\frac{1}{3}+\frac{4}{3y}$$

Whakaoti mō y

$$y=\frac{4}{3x-1}$$

$$x\neq \frac{1}{3}$$
