Kua tāruatia ki te papatopenga
2x=y-10
Tangohia te 10 mai i ngā taha e rua.
\frac{2x}{2}=\frac{y-10}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{y-10}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{y}{2}-5
Whakawehe y-10 ki te 2.
y=2x+10
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
