15x=20y
He hanga arowhānui tō te whārite.
\frac{15x}{15}=\frac{20y}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{20y}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
x=\frac{4y}{3}
Whakawehe 20y ki te 15.
20y=15x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{20y}{20}=\frac{15x}{20}
Whakawehea ngā taha e rua ki te 20.
y=\frac{15x}{20}
Mā te whakawehe ki te 20 ka wetekia te whakareanga ki te 20.
y=\frac{3x}{4}
Whakawehe 15x ki te 20.
