Kua tāruatia ki te papatopenga
3=4+3x
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 1x,3x.
4+3x=3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=3-4
Tangohia te 4 mai i ngā taha e rua.
3x=-1
Tangohia te 4 i te 3, ka -1.
x=\frac{-1}{3}
Whakawehea ngā taha e rua ki te 3.
x=-\frac{1}{3}
Ka taea te hautanga \frac{-1}{3} te tuhi anō ko -\frac{1}{3} mā te tango i te tohu tōraro.
