6-2\left(2x-1\right)=6x-\left(x-2\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 3,6.
6-4x+2=6x-\left(x-2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te 2x-1.
8-4x=6x-\left(x-2\right)
Tāpirihia te 6 ki te 2, ka 8.
8-4x=6x-x-\left(-2\right)
Hei kimi i te tauaro o x-2, kimihia te tauaro o ia taurangi.
8-4x=6x-x+2
Ko te tauaro o -2 ko 2.
8-4x=5x+2
Pahekotia te 6x me -x, ka 5x.
8-4x-5x=2
Tangohia te 5x mai i ngā taha e rua.
8-9x=2
Pahekotia te -4x me -5x, ka -9x.
-9x=2-8
Tangohia te 8 mai i ngā taha e rua.
-9x=-6
Tangohia te 8 i te 2, ka -6.
x=\frac{-6}{-9}
Whakawehea ngā taha e rua ki te -9.
x=\frac{2}{3}
Whakahekea te hautanga \frac{-6}{-9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -3.
