Whakaoti mō k
k = \frac{17}{2} = 8\frac{1}{2} = 8.5
Tohaina
Kua tāruatia ki te papatopenga
\frac{35}{2}=9+k
Whakawehea ngā taha e rua ki te 2.
9+k=\frac{35}{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
k=\frac{35}{2}-9
Tangohia te 9 mai i ngā taha e rua.
k=\frac{35}{2}-\frac{18}{2}
Me tahuri te 9 ki te hautau \frac{18}{2}.
k=\frac{35-18}{2}
Tā te mea he rite te tauraro o \frac{35}{2} me \frac{18}{2}, me tango rāua mā te tango i ō raua taurunga.
k=\frac{17}{2}
Tangohia te 18 i te 35, ka 17.
