Kua tāruatia ki te papatopenga
4x-12=0
Tē taea kia ōrite te tāupe x ki \frac{7}{3} nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 3x-7.
4x=12
Me tāpiri te 12 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{12}{4}
Whakawehea ngā taha e rua ki te 4.
x=3
Whakawehea te 12 ki te 4, kia riro ko 3.
Ngā Tauira
whārite tapawhā
