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