Whakaoti mō r
r=\frac{7s+K}{3}
Whakaoti mō K
K=3r-7s
Tohaina
Kua tāruatia ki te papatopenga
3r=K+7s
Me tāpiri te 7s ki ngā taha e rua.
3r=7s+K
He hanga arowhānui tō te whārite.
\frac{3r}{3}=\frac{7s+K}{3}
Whakawehea ngā taha e rua ki te 3.
r=\frac{7s+K}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
K=3r-7s
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
