Kua tāruatia ki te papatopenga
ab=bf+af
Tē taea kia ōrite te tāupe a ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te abf, arā, te tauraro pātahi he tino iti rawa te kitea o f,a,b.
ab-af=bf
Tangohia te af mai i ngā taha e rua.
\left(b-f\right)a=bf
Pahekotia ngā kīanga tau katoa e whai ana i te a.
\frac{\left(b-f\right)a}{b-f}=\frac{bf}{b-f}
Whakawehea ngā taha e rua ki te b-f.
a=\frac{bf}{b-f}
Mā te whakawehe ki te b-f ka wetekia te whakareanga ki te b-f.
a=\frac{bf}{b-f}\text{, }a\neq 0
Tē taea kia ōrite te tāupe a ki 0.
ab=bf+af
Tē taea kia ōrite te tāupe b ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te abf, arā, te tauraro pātahi he tino iti rawa te kitea o f,a,b.
ab-bf=af
Tangohia te bf mai i ngā taha e rua.
\left(a-f\right)b=af
Pahekotia ngā kīanga tau katoa e whai ana i te b.
\frac{\left(a-f\right)b}{a-f}=\frac{af}{a-f}
Whakawehea ngā taha e rua ki te a-f.
b=\frac{af}{a-f}
Mā te whakawehe ki te a-f ka wetekia te whakareanga ki te a-f.
b=\frac{af}{a-f}\text{, }b\neq 0
Tē taea kia ōrite te tāupe b ki 0.
