Kua tāruatia ki te papatopenga
2x=3\times 30
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 3x, arā, te tauraro pātahi he tino iti rawa te kitea o 3,x.
2x=90
Whakareatia te 3 ki te 30, ka 90.
x=\frac{90}{2}
Whakawehea ngā taha e rua ki te 2.
x=45
Whakawehea te 90 ki te 2, kia riro ko 45.
Ngā Tauira
whārite tapawhā
