Kua tāruatia ki te papatopenga
4\times 2=3x-4
Tē taea kia ōrite te tāupe x ki \frac{4}{3} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 4\left(3x-4\right), arā, te tauraro pātahi he tino iti rawa te kitea o 3x-4,4.
8=3x-4
Whakareatia te 4 ki te 2, ka 8.
3x-4=8
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=8+4
Me tāpiri te 4 ki ngā taha e rua.
3x=12
Tāpirihia te 8 ki te 4, ka 12.
x=\frac{12}{3}
Whakawehea ngā taha e rua ki te 3.
x=4
Whakawehea te 12 ki te 3, kia riro ko 4.
