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