Kua tāruatia ki te papatopenga
8x+4=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
8x=y-4
Tangohia te 4 mai i ngā taha e rua.
\frac{8x}{8}=\frac{y-4}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{y-4}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
x=\frac{y}{8}-\frac{1}{2}
Whakawehe y-4 ki te 8.
