Whakaoti mō m
m=\frac{P-n}{4}
Whakaoti mō P
P=4m+n
Tohaina
Kua tāruatia ki te papatopenga
4m+n=P
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4m=P-n
Tangohia te n mai i ngā taha e rua.
\frac{4m}{4}=\frac{P-n}{4}
Whakawehea ngā taha e rua ki te 4.
m=\frac{P-n}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
