    Step-by-step explanation:

    x + 2x + x/2 - 2 = 180

    3x + x/2 = 180 + 2

    3x + x/2 = 182 ... multiply everything by 2

    6x + x = 364

    7x = 364

    x = 364/7

    x = 52

    lets check it ...

    x + 2x + x/2 - 2 = 180

    52 + 2 (52) + 52/2 - 2 = 180

    52 + 104 + 26 - 2 = 180

    180 = 180 (correct) ... it checks out

    so x = 52 <==
