Kua tāruatia ki te papatopenga
\frac{27}{3}=2n+1
Whakawehea ngā taha e rua ki te 3.
9=2n+1
Whakawehea te 27 ki te 3, kia riro ko 9.
2n+1=9
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2n=9-1
Tangohia te 1 mai i ngā taha e rua.
2n=8
Tangohia te 1 i te 9, ka 8.
n=\frac{8}{2}
Whakawehea ngā taha e rua ki te 2.
n=4
Whakawehea te 8 ki te 2, kia riro ko 4.
