Kua tāruatia ki te papatopenga
9x=2y+3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{9x}{9}=\frac{2y+3}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{2y+3}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
x=\frac{2y}{9}+\frac{1}{3}
Whakawehe 2y+3 ki te 9.
2y=9x-3
Tangohia te 3 mai i ngā taha e rua.
\frac{2y}{2}=\frac{9x-3}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{9x-3}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
