Whakaoti i te 800*01(t-130)=-400t

$$800 \times 01 ( t - 130 ) = - 400 t$$

Whakaoti mō t

$$t=0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 800 ki te 0, ka 0.

$$0\times 1\left(t-130\right)=-400t$$

Whakareatia te 0 ki te 1, ka 0.

$$0\left(t-130\right)=-400t$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0=-400t$$

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

$$-400t=0$$

He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te -400 e ōrite ki 0, me ōrite pū te t ki 0.

$$t=0$$
