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