Whakaoti i te 66.5=7(m+3.3)

$$66.5 = 7 ( m + 3.3 )$$

Whakaoti mō m

$$m=6.2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 7.

$$\frac{66.5}{7}=m+3.3$$

Whakarohaina te \frac{66.5}{7} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{665}{70}=m+3.3$$

Whakahekea te hautanga \frac{665}{70} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 35.

$$\frac{19}{2}=m+3.3$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$m+3.3=\frac{19}{2}$$

Tangohia te 3.3 mai i ngā taha e rua.

$$m=\frac{19}{2}-3.3$$

Me tahuri ki tau ā-ira 3.3 ki te hautau \frac{33}{10}.

$$m=\frac{19}{2}-\frac{33}{10}$$

Ko te maha noa iti rawa atu o 2 me 10 ko 10. Me tahuri \frac{19}{2} me \frac{33}{10} ki te hautau me te tautūnga 10.

$$m=\frac{95}{10}-\frac{33}{10}$$

Tā te mea he rite te tauraro o \frac{95}{10} me \frac{33}{10}, me tango rāua mā te tango i ō raua taurunga.

$$m=\frac{95-33}{10}$$

Tangohia te 33 i te 95, ka 62.

$$m=\frac{62}{10}$$

Whakahekea te hautanga \frac{62}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$m=\frac{31}{5}$$
