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