Whakaoti i te 003=100x-400/407x

$$003 = 100 \frac{ x-400 }{ 407x }$$

Whakaoti mō x

$$x=400$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 407x.

$$0\times 0\times 3\times 407x=100\left(x-400\right)$$

Whakareatia te 0 ki te 0, ka 0.

$$0\times 3\times 407x=100\left(x-400\right)$$

Whakareatia te 0 ki te 3, ka 0.

$$0\times 407x=100\left(x-400\right)$$

Whakareatia te 0 ki te 407, ka 0.

$$0x=100\left(x-400\right)$$

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

$$0=100\left(x-400\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 100 ki te x-400.

$$0=100x-40000$$

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

$$100x-40000=0$$

Me tāpiri te 40000 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$100x=40000$$

Whakawehea ngā taha e rua ki te 100.

$$x=\frac{40000}{100}$$

Whakawehea te 40000 ki te 100, kia riro ko 400.

$$x=400$$
