    3x + 2 - x = 11x + 9

    First combine all the like terms:

    2x + 2 = 11x + 9

    Now subtract 2x from both sides

    2 = 9x + 9

    Now subtract 9 from both sides

    -7 = 9x

    Now divide both sides by 9 and you have solved for x.

    4x + 2 - x = 11x + 9

    combine like terms:

    3x + 2 = 11x + 9

    subtract 2 from both sides:

    3x = 11x + 7

    subtract 11x from both sides:

    -8x = 7

    divide both sides by -8:

    x = -7/8

    You made an error right at the beginning, Battleaxe. The first term is 3x+2-x not 4x+2-x. Texman's explanation is correct and the answer is x=7/9.
