Kua tāruatia ki te papatopenga
2=9x-7
Tē taea kia ōrite te tāupe x ki \frac{7}{9} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(9x-7\right), arā, te tauraro pātahi he tino iti rawa te kitea o 9x-7,2.
9x-7=2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
9x=2+7
Me tāpiri te 7 ki ngā taha e rua.
9x=9
Tāpirihia te 2 ki te 7, ka 9.
x=\frac{9}{9}
Whakawehea ngā taha e rua ki te 9.
x=1
Whakawehea te 9 ki te 9, kia riro ko 1.
