Whakaoti mō r
r=\frac{9s+K}{4}
Whakaoti mō K
K=4r-9s
Tohaina
Kua tāruatia ki te papatopenga
4r=K+9s
Me tāpiri te 9s ki ngā taha e rua.
4r=9s+K
He hanga arowhānui tō te whārite.
\frac{4r}{4}=\frac{9s+K}{4}
Whakawehea ngā taha e rua ki te 4.
r=\frac{9s+K}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
K=4r-9s
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
