Whakaoti i te 0848=frac{C_{y}*75*24*60*60}{(150)^2}

$$0848 = \frac { C _ { y } \times 75 \times 24 \times 60 \times 60 } { ( 150 ) ^ { 2 } }$$

Whakaoti mō C_y

$$C_{y}=0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0 ki te 848, ka 0.

$$0=\frac{C_{y}\times 75\times 24\times 60\times 60}{150^{2}}$$

Whakareatia te 75 ki te 24, ka 1800.

$$0=\frac{C_{y}\times 1800\times 60\times 60}{150^{2}}$$

Whakareatia te 1800 ki te 60, ka 108000.

$$0=\frac{C_{y}\times 108000\times 60}{150^{2}}$$

Whakareatia te 108000 ki te 60, ka 6480000.

$$0=\frac{C_{y}\times 6480000}{150^{2}}$$

Tātaihia te 150 mā te pū o 2, kia riro ko 22500.

$$0=\frac{C_{y}\times 6480000}{22500}$$

Whakawehea te C_{y}\times 6480000 ki te 22500, kia riro ko C_{y}\times 288.

$$0=C_{y}\times 288$$

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

$$C_{y}\times 288=0$$

He ōrite te hua o ngā tau e rua ki 0 ina 0 tētahi o rāua te iti rawa. Tātemea kāore te 288 e ōrite ki 0, me ōrite pū te C_{y} ki 0.

$$C_{y}=0$$
