80.5=6.5x
Whakareatia te 7 ki te 11.5, ka 80.5.
6.5x=80.5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{80.5}{6.5}
Whakawehea ngā taha e rua ki te 6.5.
x=\frac{805}{65}
Whakarohaina te \frac{80.5}{6.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{161}{13}
Whakahekea te hautanga \frac{805}{65} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
