Whakaoti i te 0.28=x-1.36*100000/x

$$0.28= \frac{ x-1.36 \times 100000 }{ x }$$

Whakaoti mō x

$$x = \frac{1700000}{9} = 188888\frac{8}{9} \approx 188888.888888889$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.

$$0.28x=x-1.36\times 100000$$

Whakareatia te 1.36 ki te 100000, ka 136000.

$$0.28x=x-136000$$

Tangohia te x mai i ngā taha e rua.

$$0.28x-x=-136000$$

Pahekotia te 0.28x me -x, ka -0.72x.

$$-0.72x=-136000$$

Whakawehea ngā taha e rua ki te -0.72.

$$x=\frac{-136000}{-0.72}$$

Whakarohaina te \frac{-136000}{-0.72} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{-13600000}{-72}$$

Whakahekea te hautanga \frac{-13600000}{-72} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -8.

$$x=\frac{1700000}{9}$$
