Whakaoti i te -18.56=-3.2(t-10)

$$- 18.56 = - 3.2 ( t - 10 )$$

Whakaoti mō t

$$t=15.8$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te -3.2.

$$\frac{-18.56}{-3.2}=t-10$$

Whakarohaina te \frac{-18.56}{-3.2} mā te whakarea i te taurunga me te tauraro ki te 100.

$$\frac{-1856}{-320}=t-10$$

Whakahekea te hautanga \frac{-1856}{-320} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -64.

$$\frac{29}{5}=t-10$$

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

$$t-10=\frac{29}{5}$$

Me tāpiri te 10 ki ngā taha e rua.

$$t=\frac{29}{5}+10$$

Me tahuri te 10 ki te hautau \frac{50}{5}.

$$t=\frac{29}{5}+\frac{50}{5}$$

Tā te mea he rite te tauraro o \frac{29}{5} me \frac{50}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$t=\frac{29+50}{5}$$

Tāpirihia te 29 ki te 50, ka 79.

$$t=\frac{79}{5}$$
