Kua tāruatia ki te papatopenga
5x=7y+2
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{7y+2}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{7y+2}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
7y+2=5x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
7y=5x-2
Tangohia te 2 mai i ngā taha e rua.
\frac{7y}{7}=\frac{5x-2}{7}
Whakawehea ngā taha e rua ki te 7.
y=\frac{5x-2}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
