Kua tāruatia ki te papatopenga
2\times 450=x\times 400
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2x, arā, te tauraro pātahi he tino iti rawa te kitea o x,2.
900=x\times 400
Whakareatia te 2 ki te 450, ka 900.
x\times 400=900
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{900}{400}
Whakawehea ngā taha e rua ki te 400.
x=\frac{9}{4}
Whakahekea te hautanga \frac{900}{400} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 100.
