Whakaoti i te 35000=A*250-[15000+(A*150)]

$$35000 = A \times 250 - [ 15000 + ( A \times 150 ) ]$$

Whakaoti mō A

$$A=500$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Hei kimi i te tauaro o 15000+A\times 150, kimihia te tauaro o ia taurangi.

$$35000=A\times 250-15000-A\times 150$$

Whakareatia te -1 ki te 150, ka -150.

$$35000=A\times 250-15000-150A$$

Pahekotia te A\times 250 me -150A, ka 100A.

$$35000=100A-15000$$

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

$$100A-15000=35000$$

Me tāpiri te 15000 ki ngā taha e rua.

$$100A=35000+15000$$

Tāpirihia te 35000 ki te 15000, ka 50000.

$$100A=50000$$

Whakawehea ngā taha e rua ki te 100.

$$A=\frac{50000}{100}$$

Whakawehea te 50000 ki te 100, kia riro ko 500.

$$A=500$$
