Whakaoti i te 80*18+500(2/3*18)+120x=35000

$$80 \times 18+500( \frac{ 2 }{ 3 } \times 18)+120x=35000$$

Whakaoti mō x

$$x = \frac{689}{3} = 229\frac{2}{3} \approx 229.666666667$$

Whakareatia te 80 ki te 18, ka 1440.

$$1440+500\times \frac{2}{3}\times 18+120x=35000$$

Tuhia te 500\times \frac{2}{3} hei hautanga kotahi.

$$1440+\frac{500\times 2}{3}\times 18+120x=35000$$

Whakareatia te 500 ki te 2, ka 1000.

$$1440+\frac{1000}{3}\times 18+120x=35000$$

Tuhia te \frac{1000}{3}\times 18 hei hautanga kotahi.

$$1440+\frac{1000\times 18}{3}+120x=35000$$

Whakareatia te 1000 ki te 18, ka 18000.

$$1440+\frac{18000}{3}+120x=35000$$

Whakawehea te 18000 ki te 3, kia riro ko 6000.

$$1440+6000+120x=35000$$

Tāpirihia te 1440 ki te 6000, ka 7440.

$$7440+120x=35000$$

Tangohia te 7440 mai i ngā taha e rua.

$$120x=35000-7440$$

Tangohia te 7440 i te 35000, ka 27560.

$$120x=27560$$

Whakawehea ngā taha e rua ki te 120.

$$x=\frac{27560}{120}$$

Whakahekea te hautanga \frac{27560}{120} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 40.

$$x=\frac{689}{3}$$
