Whakaoti i te 67.7=7x+6*9.2

$$67.7=7x+6 \times 9.2$$

Whakaoti mō x

$$x = \frac{25}{14} = 1\frac{11}{14} \approx 1.785714286$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 6 ki te 9.2, ka 55.2.

$$67.7=7x+55.2$$

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

$$7x+55.2=67.7$$

Tangohia te 55.2 mai i ngā taha e rua.

$$7x=67.7-55.2$$

Tangohia te 55.2 i te 67.7, ka 12.5.

$$7x=12.5$$

Whakawehea ngā taha e rua ki te 7.

$$x=\frac{12.5}{7}$$

Whakarohaina te \frac{12.5}{7} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{125}{70}$$

Whakahekea te hautanga \frac{125}{70} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x=\frac{25}{14}$$
