Whakaoti mō B
B=\frac{A-C}{5}
Whakaoti mō A
A=5B+C
Tohaina
Kua tāruatia ki te papatopenga
5B+C=A
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5B=A-C
Tangohia te C mai i ngā taha e rua.
\frac{5B}{5}=\frac{A-C}{5}
Whakawehea ngā taha e rua ki te 5.
B=\frac{A-C}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
