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

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

Whakaoti mō x

$$x=\frac{-y-5}{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

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

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

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

Me tāpiri te 4 ki ngā taha e rua.

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

Tāpirihia te 1 ki te 4, ka 5.

$$-2x=y+5$$

Whakawehea ngā taha e rua ki te -2.

$$\frac{-2x}{-2}=\frac{y+5}{-2}$$

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

$$x=\frac{y+5}{-2}$$

Whakawehe y+5 ki te -2.

$$x=\frac{-y-5}{2}$$

Whakaoti mō y

$$y=-2x-5$$

Ngā Upane Otinga

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

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

Tangohia te 1 mai i ngā taha e rua.

$$y=-2x-4-1$$

Tangohia te 1 i te -4, ka -5.

$$y=-2x-5$$
