Whakaoti i te 2x+7-5x-12=-8y+3

$$2 x + 7 - 5 x - 12 = - 8 y + 3$$

Whakaoti mō x

$$x=\frac{8\left(y-1\right)}{3}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te 2x me -5x, ka -3x.

$$-3x+7-12=-8y+3$$

Tangohia te 12 i te 7, ka -5.

$$-3x-5=-8y+3$$

Me tāpiri te 5 ki ngā taha e rua.

$$-3x=-8y+3+5$$

Tāpirihia te 3 ki te 5, ka 8.

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

He hanga arowhānui tō te whārite.

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

Whakawehea ngā taha e rua ki te -3.

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

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

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

Whakawehe -8y+8 ki te -3.

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

Whakaoti mō y

$$y=\frac{3x}{8}+1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te 2x me -5x, ka -3x.

$$-3x+7-12=-8y+3$$

Tangohia te 12 i te 7, ka -5.

$$-3x-5=-8y+3$$

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

$$-8y+3=-3x-5$$

Tangohia te 3 mai i ngā taha e rua.

$$-8y=-3x-5-3$$

Tangohia te 3 i te -5, ka -8.

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

Whakawehea ngā taha e rua ki te -8.

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

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

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

Whakawehe -3x-8 ki te -8.

$$y=\frac{3x}{8}+1$$
