Kua tāruatia ki te papatopenga
7x=5y
He hanga arowhānui tō te whārite.
\frac{7x}{7}=\frac{5y}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{5y}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
5y=7x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{5y}{5}=\frac{7x}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{7x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
