Whakaoti i te (x*.07*1)+((x-1700)*.06*1)=223

$$(x \times .07 \times 1)+((x-1700) \times .06 \times 1)=223$$

Whakaoti mō x

$$x=2500$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0.07 ki te 1, ka 0.07.

$$x\times 0.07+\left(x-1700\right)\times 0.06\times 1=223$$

Whakareatia te 0.06 ki te 1, ka 0.06.

$$x\times 0.07+\left(x-1700\right)\times 0.06=223$$

Whakamahia te āhuatanga tohatoha hei whakarea te x-1700 ki te 0.06.

$$x\times 0.07+0.06x-102=223$$

Pahekotia te x\times 0.07 me 0.06x, ka 0.13x.

$$0.13x-102=223$$

Me tāpiri te 102 ki ngā taha e rua.

$$0.13x=223+102$$

Tāpirihia te 223 ki te 102, ka 325.

$$0.13x=325$$

Whakawehea ngā taha e rua ki te 0.13.

$$x=\frac{325}{0.13}$$

Whakarohaina te \frac{325}{0.13} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{32500}{13}$$

Whakawehea te 32500 ki te 13, kia riro ko 2500.

$$x=2500$$
