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