Kua tāruatia ki te papatopenga
yx=dx
Whakareatia ngā taha e rua o te whārite ki te x.
dx=yx
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
xd=xy
He hanga arowhānui tō te whārite.
\frac{xd}{x}=\frac{xy}{x}
Whakawehea ngā taha e rua ki te x.
d=\frac{xy}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
d=y
Whakawehe yx ki te x.
yx=dx
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.
yx-dx=0
Tangohia te dx mai i ngā taha e rua.
\left(y-d\right)x=0
Pahekotia ngā kīanga tau katoa e whai ana i te x.
x=0
Whakawehe 0 ki te y-d.
x\in \emptyset
Tē taea kia ōrite te tāupe x ki 0.
