Kua tāruatia ki te papatopenga
4-3x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3x=y-4
Tangohia te 4 mai i ngā taha e rua.
\frac{-3x}{-3}=\frac{y-4}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{y-4}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
x=\frac{4-y}{3}
Whakawehe y-4 ki te -3.
