Kua tāruatia ki te papatopenga
3=3\left(x-1\right)\times \frac{2}{3}+3\times 2
Tē taea kia ōrite te tāupe x ki 1 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 3\left(x-1\right), arā, te tauraro pātahi he tino iti rawa te kitea o x-1,3.
3=2\left(x-1\right)+3\times 2
Whakareatia te 3 ki te \frac{2}{3}, ka 2.
3=2x-2+3\times 2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-1.
3=2x-2+6
Whakareatia te 3 ki te 2, ka 6.
3=2x+4
Tāpirihia te -2 ki te 6, ka 4.
2x+4=3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=3-4
Tangohia te 4 mai i ngā taha e rua.
2x=-1
Tangohia te 4 i te 3, ka -1.
x=\frac{-1}{2}
Whakawehea ngā taha e rua ki te 2.
x=-\frac{1}{2}
Ka taea te hautanga \frac{-1}{2} te tuhi anō ko -\frac{1}{2} mā te tango i te tohu tōraro.
