Kua tāruatia ki te papatopenga
21=7x
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.
7x=21
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{21}{7}
Whakawehea ngā taha e rua ki te 7.
x=3
Whakawehea te 21 ki te 7, kia riro ko 3.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
