Kua tāruatia ki te papatopenga
3x=2y-5
Tangohia te 5 mai i ngā taha e rua.
\frac{3x}{3}=\frac{2y-5}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{2y-5}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
2y=3x+5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{2y}{2}=\frac{3x+5}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{3x+5}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
