x-2+\left(x-4\right)\times 2=2x-3
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara 2,4 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(x-4\right)\left(x-2\right), arā, te tauraro pātahi he tino iti rawa te kitea o x-4,x-2,x^{2}-6x+8.
x-2+2x-8=2x-3
Whakamahia te āhuatanga tohatoha hei whakarea te x-4 ki te 2.
3x-2-8=2x-3
Pahekotia te x me 2x, ka 3x.
3x-10=2x-3
Tangohia te 8 i te -2, ka -10.
3x-10-2x=-3
Tangohia te 2x mai i ngā taha e rua.
x-10=-3
Pahekotia te 3x me -2x, ka x.
x=-3+10
Me tāpiri te 10 ki ngā taha e rua.
x=7
Tāpirihia te -3 ki te 10, ka 7.
