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