Whakaoti i te y-8=-5(x+4)

$$y - 8 = - 5 ( x + 4 )$$

Whakaoti mō x

$$x=\frac{-y-12}{5}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x+4.

$$y-8=-5x-20$$

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

$$-5x-20=y-8$$

Me tāpiri te 20 ki ngā taha e rua.

$$-5x=y-8+20$$

Tāpirihia te -8 ki te 20, ka 12.

$$-5x=y+12$$

Whakawehea ngā taha e rua ki te -5.

$$\frac{-5x}{-5}=\frac{y+12}{-5}$$

Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.

$$x=\frac{y+12}{-5}$$

Whakawehe y+12 ki te -5.

$$x=\frac{-y-12}{5}$$

Whakaoti mō y

$$y=-5x-12$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te x+4.

$$y-8=-5x-20$$

Me tāpiri te 8 ki ngā taha e rua.

$$y=-5x-20+8$$

Tāpirihia te -20 ki te 8, ka -12.

$$y=-5x-12$$
