    1/2 X + X - 15 + 1/2 X + 100 + X - 25 = 540

    1/2x + x + 1/2x + x - 15 + 100 - 25 = 540

    3 x + 60 = 540

    3x + 60 - 60 = 540 - 60

    3/3x = 480/3

    x = 160

    Step-by-step explanation:

    1/2 X + X - 15 + 1/2 X + 100 + X - 25 = 540

    1/2x + x + 1/2x + x - 15 + 100 - 25 = 540

    3 x + 60 = 540

    3x + 60 - 60 = 540 - 60

    3/3x = 480/3

    x = 160
