Whakaoti i te y+4=-2(x-1)

$$y + 4 = - 2 ( x - 1 )$$

Whakaoti mō x

$$x=-\frac{y}{2}-1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-1.

$$y+4=-2x+2$$

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

$$-2x+2=y+4$$

Tangohia te 2 mai i ngā taha e rua.

$$-2x=y+4-2$$

Tangohia te 2 i te 4, ka 2.

$$-2x=y+2$$

Whakawehea ngā taha e rua ki te -2.

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

Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.

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

Whakawehe y+2 ki te -2.

$$x=-\frac{y}{2}-1$$

Whakaoti mō y

$$y=-2x-2$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-1.

$$y+4=-2x+2$$

Tangohia te 4 mai i ngā taha e rua.

$$y=-2x+2-4$$

Tangohia te 4 i te 2, ka -2.

$$y=-2x-2$$
