Tohaina
Kua tāruatia ki te papatopenga
1-5=ab
Whakareatia ngā taha e rua o te whārite ki te b.
-4=ab
Tangohia te 5 i te 1, ka -4.
ab=-4
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
ba=-4
He hanga arowhānui tō te whārite.
\frac{ba}{b}=-\frac{4}{b}
Whakawehea ngā taha e rua ki te b.
a=-\frac{4}{b}
Mā te whakawehe ki te b ka wetekia te whakareanga ki te b.
1-5=ab
Tē taea kia ōrite te tāupe b ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te b.
-4=ab
Tangohia te 5 i te 1, ka -4.
ab=-4
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{ab}{a}=-\frac{4}{a}
Whakawehea ngā taha e rua ki te a.
b=-\frac{4}{a}
Mā te whakawehe ki te a ka wetekia te whakareanga ki te a.
b=-\frac{4}{a}\text{, }b\neq 0
Tē taea kia ōrite te tāupe b ki 0.
