    2x - 8 = 3x + 2 + x - 6

    2x-8 = 3x+x+2-6

    2x-8 = 4x-4

    Move 4x to the other side.

    Sign changes from + 4x to - 4x.

    2x-4x-8 = 4x-4x-4

    2x-4x-8=-4

    -2x-8 = - 4

    move - 8 to the other side

    sign changes from - 8 to + 8

    -2x-8+8 = - 4+8

    -2x = 4

    divide by - 2

    -2x/-2=-4/2

    cross out - 2 and - 2, divide by 2 and then becomes x

    x = - 2

    Answer : x = - 2
