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