Kua tāruatia ki te papatopenga
4x-12=3\left(x-2\right)
Tē taea kia ōrite te tāupe x ki 2 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x-2.
4x-12=3x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-2.
4x-12-3x=-6
Tangohia te 3x mai i ngā taha e rua.
x-12=-6
Pahekotia te 4x me -3x, ka x.
x=-6+12
Me tāpiri te 12 ki ngā taha e rua.
x=6
Tāpirihia te -6 ki te 12, ka 6.
