    18x + 30 = 12x - 6

    Balance the equation.

    6x + 30 = - 6

    Get 6x by itself

    6x = - 36

    Divide by 6

    x = - 6

    18x + 30 = 12x - 6

    -12x. - 12x

    minus 12x from both sides.

    6x + 30 = - 6

    -30. - 30

    minus 30 from both sides.

    6x = - 36

    divide - 36 by 6

    -36/6 = - 6

    x = - 6
