Whakaoti mō Q
Q=1800-15P
Tohaina
Kua tāruatia ki te papatopenga
1800-15P=Q
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-15P=Q-1800
Tangohia te 1800 mai i ngā taha e rua.
\frac{-15P}{-15}=\frac{Q-1800}{-15}
Whakawehea ngā taha e rua ki te -15.
P=\frac{Q-1800}{-15}
Mā te whakawehe ki te -15 ka wetekia te whakareanga ki te -15.
P=-\frac{Q}{15}+120
Whakawehe Q-1800 ki te -15.
