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