Kua tāruatia ki te papatopenga
8x=5y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{8x}{8}=\frac{5y}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{5y}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
5y=8x
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{8x}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{8x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
