Tohaina
Kua tāruatia ki te papatopenga
15+\frac{5d}{12}=P
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{5d}{12}=P-15
Tangohia te 15 mai i ngā taha e rua.
5d=12P-180
Whakareatia ngā taha e rua o te whārite ki te 12.
\frac{5d}{5}=\frac{12P-180}{5}
Whakawehea ngā taha e rua ki te 5.
d=\frac{12P-180}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
d=\frac{12P}{5}-36
Whakawehe -180+12P ki te 5.
