Kua tāruatia ki te papatopenga
2\tan(45)x=16
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.
\frac{2\tan(45)x}{2\tan(45)}=\frac{16}{2\tan(45)}
Whakawehea ngā taha e rua ki te 2\tan(45).
x=\frac{16}{2\tan(45)}
Mā te whakawehe ki te 2\tan(45) ka wetekia te whakareanga ki te 2\tan(45).
x=8\cot(45)
Whakawehe 16 ki te 2\tan(45).
