    4x = 8 + 2x

    Take 2x from the right side to the left side.

    When a term change sides in an equation, it sign changes.

    (Another way of looking at it: subtract 2x from both sides)

    Hence

    4x - 2x = 8

    (4 -2)x = 8

    2x = 8

    Divide both sides by 2

    x = 8/2

    x = 4
