Kua tāruatia ki te papatopenga
-3x-2=2y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3x=2y+2
Me tāpiri te 2 ki ngā taha e rua.
\frac{-3x}{-3}=\frac{2y+2}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{2y+2}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
x=\frac{-2y-2}{3}
Whakawehe 2+2y ki te -3.
2y=-3x-2
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{-3x-2}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{-3x-2}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{3x}{2}-1
Whakawehe -3x-2 ki te 2.
