Tohaina
Kua tāruatia ki te papatopenga
12\times 7=z\times 84
Tē taea kia ōrite te tāupe z ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 12z, arā, te tauraro pātahi he tino iti rawa te kitea o z,12.
84=z\times 84
Whakareatia te 12 ki te 7, ka 84.
z\times 84=84
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
z=\frac{84}{84}
Whakawehea ngā taha e rua ki te 84.
z=1
Whakawehea te 84 ki te 84, kia riro ko 1.
