Whakaoti i te 0.14*500/500+x=0.1

$$\frac{ 0.14 \cdot 500 }{ 500+x } = 0.1$$

Whakaoti mō x

$$x=200$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki -500 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+500.

$$0.14\times 500=0.1\left(x+500\right)$$

Whakareatia te 0.14 ki te 500, ka 70.

$$70=0.1\left(x+500\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 0.1 ki te x+500.

$$70=0.1x+50$$

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

$$0.1x+50=70$$

Tangohia te 50 mai i ngā taha e rua.

$$0.1x=70-50$$

Tangohia te 50 i te 70, ka 20.

$$0.1x=20$$

Whakawehea ngā taha e rua ki te 0.1.

$$x=\frac{20}{0.1}$$

Whakarohaina te \frac{20}{0.1} mā te whakarea i te taurunga me te tauraro ki te 10. Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$x=200$$
