Whakaoti i te 12xdiv5^2*15+44=74

$$12x \div { 5 }^{ 2 } \times 15+44=74$$

Whakaoti mō x

$$x = \frac{25}{6} = 4\frac{1}{6} \approx 4.166666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 5 mā te pū o 2, kia riro ko 25.

$$\frac{12x}{25}\times 15+44=74$$

Tuhia te \frac{12x}{25}\times 15 hei hautanga kotahi.

$$\frac{12x\times 15}{25}+44=74$$

Whakareatia te 12 ki te 15, ka 180.

$$\frac{180x}{25}+44=74$$

Whakawehea te 180x ki te 25, kia riro ko \frac{36}{5}x.

$$\frac{36}{5}x+44=74$$

Tangohia te 44 mai i ngā taha e rua.

$$\frac{36}{5}x=74-44$$

Tangohia te 44 i te 74, ka 30.

$$\frac{36}{5}x=30$$

Me whakarea ngā taha e rua ki te \frac{5}{36}, te tau utu o \frac{36}{5}.

$$x=30\times \frac{5}{36}$$

Tuhia te 30\times \frac{5}{36} hei hautanga kotahi.

$$x=\frac{30\times 5}{36}$$

Whakareatia te 30 ki te 5, ka 150.

$$x=\frac{150}{36}$$

Whakahekea te hautanga \frac{150}{36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$x=\frac{25}{6}$$
