2fx=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2xf=y
He hanga arowhānui tō te whārite.
\frac{2xf}{2x}=\frac{y}{2x}
Whakawehea ngā taha e rua ki te 2x.
f=\frac{y}{2x}
Mā te whakawehe ki te 2x ka wetekia te whakareanga ki te 2x.
2fx=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{2fx}{2f}=\frac{y}{2f}
Whakawehea ngā taha e rua ki te 2f.
x=\frac{y}{2f}
Mā te whakawehe ki te 2f ka wetekia te whakareanga ki te 2f.
