6x+8=8x-28
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4x-14.
6x+8-8x=-28
Tangohia te 8x mai i ngā taha e rua.
-2x+8=-28
Pahekotia te 6x me -8x, ka -2x.
-2x=-28-8
Tangohia te 8 mai i ngā taha e rua.
-2x=-36
Tangohia te 8 i te -28, ka -36.
x=\frac{-36}{-2}
Whakawehea ngā taha e rua ki te -2.
x=18
Whakawehea te -36 ki te -2, kia riro ko 18.
