Kua tāruatia ki te papatopenga
\left(x-1\right)\times 8=\left(3x-2\right)\times 2
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara \frac{2}{3},1 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(x-1\right)\left(3x-2\right), arā, te tauraro pātahi he tino iti rawa te kitea o 3x-2,x-1.
8x-8=\left(3x-2\right)\times 2
Whakamahia te āhuatanga tohatoha hei whakarea te x-1 ki te 8.
8x-8=6x-4
Whakamahia te āhuatanga tohatoha hei whakarea te 3x-2 ki te 2.
8x-8-6x=-4
Tangohia te 6x mai i ngā taha e rua.
2x-8=-4
Pahekotia te 8x me -6x, ka 2x.
2x=-4+8
Me tāpiri te 8 ki ngā taha e rua.
2x=4
Tāpirihia te -4 ki te 8, ka 4.
x=\frac{4}{2}
Whakawehea ngā taha e rua ki te 2.
x=2
Whakawehea te 4 ki te 2, kia riro ko 2.
