Whakaoti i te 4(x+1.4)=9.84

$$4(x+1.4)=9.84$$

Whakaoti mō x

$$x=1.06$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 4.

$$x+1.4=\frac{9.84}{4}$$

Whakarohaina te \frac{9.84}{4} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x+1.4=\frac{984}{400}$$

Whakahekea te hautanga \frac{984}{400} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.

$$x+1.4=\frac{123}{50}$$

Tangohia te 1.4 mai i ngā taha e rua.

$$x=\frac{123}{50}-1.4$$

Me tahuri ki tau ā-ira 1.4 ki te hautau \frac{14}{10}. Whakahekea te hautanga \frac{14}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{123}{50}-\frac{7}{5}$$

Ko te maha noa iti rawa atu o 50 me 5 ko 50. Me tahuri \frac{123}{50} me \frac{7}{5} ki te hautau me te tautūnga 50.

$$x=\frac{123}{50}-\frac{70}{50}$$

Tā te mea he rite te tauraro o \frac{123}{50} me \frac{70}{50}, me tango rāua mā te tango i ō raua taurunga.

$$x=\frac{123-70}{50}$$

Tangohia te 70 i te 123, ka 53.

$$x=\frac{53}{50}$$
