    Answer: x≈ 14. 08

    Step-by-step explanation:

    Given:

    3x - 1 + 9x - 7 + 19 = 180

    The first thing is to collect the like term, then we have

    3x + 9x - 1 - 7 + 19 = 180

    12x + 11 = 180

    subtract 11 from both sides

    12x = 180 - 11

    12x = 169

    divide through by 12

    x = 169/12

    x = 14.083333333333

    x≈ 14. 08
