Kua tāruatia ki te papatopenga
fx=gx
Whakareatia ngā taha e rua o te whārite ki te gx.
xf=gx
He hanga arowhānui tō te whārite.
\frac{xf}{x}=\frac{gx}{x}
Whakawehea ngā taha e rua ki te x.
f=\frac{gx}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
f=g
Whakawehe gx ki te x.
fx=gx
Tē taea kia ōrite te tāupe g ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te gx.
gx=fx
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
xg=fx
He hanga arowhānui tō te whārite.
\frac{xg}{x}=\frac{fx}{x}
Whakawehea ngā taha e rua ki te x.
g=\frac{fx}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
g=f
Whakawehe fx ki te x.
g=f\text{, }g\neq 0
Tē taea kia ōrite te tāupe g ki 0.
