Whakaoti i te 4-3y=-20-8x

$$4 - 3 y = - 20 - 8 x$$

Whakaoti mō x

$$x=\frac{3\left(y-8\right)}{8}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$-20-8x=4-3y$$

Me tāpiri te 20 ki ngā taha e rua.

$$-8x=4-3y+20$$

Tāpirihia te 4 ki te 20, ka 24.

$$-8x=24-3y$$

Whakawehea ngā taha e rua ki te -8.

$$\frac{-8x}{-8}=\frac{24-3y}{-8}$$

Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.

$$x=\frac{24-3y}{-8}$$

Whakawehe 24-3y ki te -8.

$$x=\frac{3y}{8}-3$$

Whakaoti mō y

$$y=\frac{8\left(x+3\right)}{3}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 4 mai i ngā taha e rua.

$$-3y=-20-8x-4$$

Tangohia te 4 i te -20, ka -24.

$$-3y=-24-8x$$

He hanga arowhānui tō te whārite.

$$-3y=-8x-24$$

Whakawehea ngā taha e rua ki te -3.

$$\frac{-3y}{-3}=\frac{-8x-24}{-3}$$

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

$$y=\frac{-8x-24}{-3}$$

Whakawehe -24-8x ki te -3.

$$y=\frac{8x}{3}+8$$
