Tohaina
Kua tāruatia ki te papatopenga
-12=-3v
Tē taea kia ōrite te tāupe v ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te v.
-3v=-12
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
v=\frac{-12}{-3}
Whakawehea ngā taha e rua ki te -3.
v=4
Whakawehea te -12 ki te -3, kia riro ko 4.
