Whakaoti i te x+x+0.8+x+0.5=50.7

$$x+x+0.8+x+0.5=50.7$$

Whakaoti mō x

$$x = \frac{247}{15} = 16\frac{7}{15} \approx 16.466666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te x me x, ka 2x.

$$2x+0.8+x+0.5=50.7$$

Pahekotia te 2x me x, ka 3x.

$$3x+0.8+0.5=50.7$$

Tāpirihia te 0.8 ki te 0.5, ka 1.3.

$$3x+1.3=50.7$$

Tangohia te 1.3 mai i ngā taha e rua.

$$3x=50.7-1.3$$

Tangohia te 1.3 i te 50.7, ka 49.4.

$$3x=49.4$$

Whakawehea ngā taha e rua ki te 3.

$$x=\frac{49.4}{3}$$

Whakarohaina te \frac{49.4}{3} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{494}{30}$$

Whakahekea te hautanga \frac{494}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{247}{15}$$
