Whakaoti i te 180x=2(30div3)+17-5*11+2div1

$$180 x = 2 ( 30 \div 3 ) + 17 - 5 \cdot 11 + 2 \div 1$$

Whakaoti mō x

$$x=-\frac{4}{45}\approx -0.088888889$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea te 30 ki te 3, kia riro ko 10.

$$180x=2\times 10+17-5\times 11+\frac{2}{1}$$

Whakareatia te 2 ki te 10, ka 20.

$$180x=20+17-5\times 11+\frac{2}{1}$$

Tāpirihia te 20 ki te 17, ka 37.

$$180x=37-5\times 11+\frac{2}{1}$$

Whakareatia te 5 ki te 11, ka 55.

$$180x=37-55+\frac{2}{1}$$

Tangohia te 55 i te 37, ka -18.

$$180x=-18+\frac{2}{1}$$

Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$180x=-18+2$$

Tāpirihia te -18 ki te 2, ka -16.

$$180x=-16$$

Whakawehea ngā taha e rua ki te 180.

$$x=\frac{-16}{180}$$

Whakahekea te hautanga \frac{-16}{180} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x=-\frac{4}{45}$$
