Kua tāruatia ki te papatopenga
-4a=y-4789
Tangohia te 4789 mai i ngā taha e rua.
\frac{-4a}{-4}=\frac{y-4789}{-4}
Whakawehea ngā taha e rua ki te -4.
a=\frac{y-4789}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
a=\frac{4789-y}{4}
Whakawehe y-4789 ki te -4.
y=4789-4a
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
