Kua tāruatia ki te papatopenga
20=1.6x
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.
1.6x=20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{20}{1.6}
Whakawehea ngā taha e rua ki te 1.6.
x=\frac{200}{16}
Whakarohaina te \frac{20}{1.6} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{25}{2}
Whakahekea te hautanga \frac{200}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.
