Kua tāruatia ki te papatopenga
2\pi =15x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.
15x=2\pi
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{15x}{15}=\frac{2\pi }{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{2\pi }{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
x=\frac{2\pi }{15}\text{, }x\neq 0
Tē taea kia ōrite te tāupe x ki 0.
