Kua tāruatia ki te papatopenga
9\times 7=x\times 15
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 9x, arā, te tauraro pātahi he tino iti rawa te kitea o x,9.
63=x\times 15
Whakareatia te 9 ki te 7, ka 63.
x\times 15=63
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{63}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{21}{5}
Whakahekea te hautanga \frac{63}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
