Whakaoti i te 411pi=pi*129*x+pi*129^2

$$411 \pi = \pi \times 129 \times x+ \pi \times { 129 }^{ 2 }$$

Whakaoti mō x

$$x = -\frac{5410}{43} = -125\frac{35}{43} \approx -125.813953488$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 129 mā te pū o 2, kia riro ko 16641.

$$411\pi =\pi \times 129x+\pi \times 16641$$

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

$$\pi \times 129x+\pi \times 16641=411\pi$$

Tangohia te \pi \times 16641 mai i ngā taha e rua.

$$\pi \times 129x=411\pi -\pi \times 16641$$

Pahekotia te 411\pi me -\pi \times 16641, ka -16230\pi .

$$\pi \times 129x=-16230\pi$$

Me whakakore te \pi ki ngā taha e rua.

$$129x=-16230$$

Whakawehea ngā taha e rua ki te 129.

$$x=\frac{-16230}{129}$$

Whakahekea te hautanga \frac{-16230}{129} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x=-\frac{5410}{43}$$
