3\left(x+3\right)-2\left(x-2\right)=6x-1+4
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3,6.
3x+9-2\left(x-2\right)=6x-1+4
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+3.
3x+9-2x+4=6x-1+4
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-2.
x+9+4=6x-1+4
Pahekotia te 3x me -2x, ka x.
x+13=6x-1+4
Tāpirihia te 9 ki te 4, ka 13.
x+13=6x+3
Tāpirihia te -1 ki te 4, ka 3.
x+13-6x=3
Tangohia te 6x mai i ngā taha e rua.
-5x+13=3
Pahekotia te x me -6x, ka -5x.
-5x=3-13
Tangohia te 13 mai i ngā taha e rua.
-5x=-10
Tangohia te 13 i te 3, ka -10.
x=\frac{-10}{-5}
Whakawehea ngā taha e rua ki te -5.
x=2
Whakawehea te -10 ki te -5, kia riro ko 2.
