Whakaoti mō r
r=\frac{5s+K}{2}
Whakaoti mō K
K=2r-5s
Tohaina
Kua tāruatia ki te papatopenga
2r-5s=K
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2r=K+5s
Me tāpiri te 5s ki ngā taha e rua.
2r=5s+K
He hanga arowhānui tō te whārite.
\frac{2r}{2}=\frac{5s+K}{2}
Whakawehea ngā taha e rua ki te 2.
r=\frac{5s+K}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
