    x + 2017/2 + x + 2017/4 + x + 2017/12 = 3/4
    ( x + x + x ) + ( 2017/2 + 2017/4 + 2017/12) = 3/4
    3x + 10085/6 = 3/4
    3x = 3/4 – 10085/6
    3x=-20161/12
    x = -20161/12 : 3
    x=-20161/36

    x + 2017/2 + x + 2017/4 + x + 2017/12 = 3/4
    ( x × 3 ) + ( 2017/2 + 2017/4 + 2017/12 ) = 3/4
    ( x × 3 ) + 10085/6 = 3/4
    x × 3 = 3/4 – 10085/6
    x × 3 = -20161/12
           x = -20161/12 : 3
           x = -20161/36
