Kua tāruatia ki te papatopenga
20=16x
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.
16x=20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{20}{16}
Whakawehea ngā taha e rua ki te 16.
x=\frac{5}{4}
Whakahekea te hautanga \frac{20}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
