8-2x+6=4+2\left(x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-3.
14-2x=4+2\left(x-3\right)
Tāpirihia te 8 ki te 6, ka 14.
14-2x=4+2x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-3.
14-2x=-2+2x
Tangohia te 6 i te 4, ka -2.
14-2x-2x=-2
Tangohia te 2x mai i ngā taha e rua.
14-4x=-2
Pahekotia te -2x me -2x, ka -4x.
-4x=-2-14
Tangohia te 14 mai i ngā taha e rua.
-4x=-16
Tangohia te 14 i te -2, ka -16.
x=\frac{-16}{-4}
Whakawehea ngā taha e rua ki te -4.
x=4
Whakawehea te -16 ki te -4, kia riro ko 4.
