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