Kua tāruatia ki te papatopenga
2x=3+2\left(x-1\right)\left(-2\right)
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 2\left(x-1\right), arā, te tauraro pātahi he tino iti rawa te kitea o x-1,2x-2.
2x=3-4\left(x-1\right)
Whakareatia te 2 ki te -2, ka -4.
2x=3-4x+4
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x-1.
2x=7-4x
Tāpirihia te 3 ki te 4, ka 7.
2x+4x=7
Me tāpiri te 4x ki ngā taha e rua.
6x=7
Pahekotia te 2x me 4x, ka 6x.
x=\frac{7}{6}
Whakawehea ngā taha e rua ki te 6.
