Kua tāruatia ki te papatopenga
1=1.5x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.
1.5x=1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{1}{1.5}
Whakawehea ngā taha e rua ki te 1.5.
x=\frac{10}{15}
Whakarohaina te \frac{1}{1.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{2}{3}
Whakahekea te hautanga \frac{10}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
