Whakaoti i te (x*.05*1)+((x-1500)*.04*1)=156

$$(x \times .05 \times 1)+((x-1500) \times .04 \times 1)=156$$

Whakaoti mō x

$$x=2400$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0.05 ki te 1, ka 0.05.

$$x\times 0.05+\left(x-1500\right)\times 0.04\times 1=156$$

Whakareatia te 0.04 ki te 1, ka 0.04.

$$x\times 0.05+\left(x-1500\right)\times 0.04=156$$

Whakamahia te āhuatanga tohatoha hei whakarea te x-1500 ki te 0.04.

$$x\times 0.05+0.04x-60=156$$

Pahekotia te x\times 0.05 me 0.04x, ka 0.09x.

$$0.09x-60=156$$

Me tāpiri te 60 ki ngā taha e rua.

$$0.09x=156+60$$

Tāpirihia te 156 ki te 60, ka 216.

$$0.09x=216$$

Whakawehea ngā taha e rua ki te 0.09.

$$x=\frac{216}{0.09}$$

Whakarohaina te \frac{216}{0.09} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{21600}{9}$$

Whakawehea te 21600 ki te 9, kia riro ko 2400.

$$x=2400$$
