Whakaoti i te 2268=4167*P/8000-9*P/20

$$2268 = \frac { 4167 \times P } { 8000 } - \frac { 9 \times P } { 20 }$$

Whakaoti mō P

$$P=32000$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 8000, arā, te tauraro pātahi he tino iti rawa te kitea o 8000,20.

$$18144000=4167P-400\times 9P$$

Whakareatia te -400 ki te 9, ka -3600.

$$18144000=4167P-3600P$$

Pahekotia te 4167P me -3600P, ka 567P.

$$18144000=567P$$

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

$$567P=18144000$$

Whakawehea ngā taha e rua ki te 567.

$$P=\frac{18144000}{567}$$

Whakawehea te 18144000 ki te 567, kia riro ko 32000.

$$P=32000$$
