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