    x in (-oo:+oo)

    (x+20) / 2 = 3*x / / - 3*x

    (x+20) / 2 - (3*x) = 0

    (x+20) / 2-3*x = 0

    (x+20) / 2 + (-3*2*x) / 2 = 0

    x-3*2*x+20 = 0

    20-5*x = 0

    (20-5*x) / 2 = 0

    (20-5*x) / 2 = 0 / / * 2

    20-5*x = 0

    20-5*x = 0 / / - 20

    -5*x = - 20 / / : - 5

    x = - 20 / (-5)

    x = 4 so x = 4
