Whakaoti i te (x*621%*6)+x=18

$$( x \cdot 621 \% \cdot 6 ) + x = 18$$

Whakaoti mō x

$$x=\frac{900}{1913}\approx 0.470465238$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tuhia te \frac{621}{100}\times 6 hei hautanga kotahi.

$$x\times \frac{621\times 6}{100}+x=18$$

Whakareatia te 621 ki te 6, ka 3726.

$$x\times \frac{3726}{100}+x=18$$

Whakahekea te hautanga \frac{3726}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x\times \frac{1863}{50}+x=18$$

Pahekotia te x\times \frac{1863}{50} me x, ka \frac{1913}{50}x.

$$\frac{1913}{50}x=18$$

Me whakarea ngā taha e rua ki te \frac{50}{1913}, te tau utu o \frac{1913}{50}.

$$x=18\times \frac{50}{1913}$$

Tuhia te 18\times \frac{50}{1913} hei hautanga kotahi.

$$x=\frac{18\times 50}{1913}$$

Whakareatia te 18 ki te 50, ka 900.

$$x=\frac{900}{1913}$$
