-3\left(x-2\right)+4\left(x-2\right)+4\left(x-2\right)=6\left(x-1\right)-3
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,3,2.
-3x+6+4\left(x-2\right)+4\left(x-2\right)=6\left(x-1\right)-3
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-2.
-3x+6+4x-8+4\left(x-2\right)=6\left(x-1\right)-3
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-2.
x+6-8+4\left(x-2\right)=6\left(x-1\right)-3
Pahekotia te -3x me 4x, ka x.
x-2+4\left(x-2\right)=6\left(x-1\right)-3
Tangohia te 8 i te 6, ka -2.
x-2+4x-8=6\left(x-1\right)-3
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x-2.
5x-2-8=6\left(x-1\right)-3
Pahekotia te x me 4x, ka 5x.
5x-10=6\left(x-1\right)-3
Tangohia te 8 i te -2, ka -10.
5x-10=6x-6-3
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te x-1.
5x-10=6x-9
Tangohia te 3 i te -6, ka -9.
5x-10-6x=-9
Tangohia te 6x mai i ngā taha e rua.
-x-10=-9
Pahekotia te 5x me -6x, ka -x.
-x=-9+10
Me tāpiri te 10 ki ngā taha e rua.
-x=1
Tāpirihia te -9 ki te 10, ka 1.
x=-1
Me whakarea ngā taha e rua ki te -1.
