Tohaina
Kua tāruatia ki te papatopenga
3\times 3=n-4+2
Tē taea kia ōrite te tāupe n ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 3n^{2}, arā, te tauraro pātahi he tino iti rawa te kitea o n^{2},3n^{2}.
9=n-4+2
Whakareatia te 3 ki te 3, ka 9.
9=n-2
Tāpirihia te -4 ki te 2, ka -2.
n-2=9
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
n=9+2
Me tāpiri te 2 ki ngā taha e rua.
n=11
Tāpirihia te 9 ki te 2, ka 11.
