    Explanation:

    8x2-41x+5=0
    8x2 -40x-x+5=0
    8x(x -5) – 1(x -5)=0
    (x-5) ( 8x-1)=0
    x= 5 , 1/8
    49y2-49y-18=0
    49y2 -63y+ 14y -18=0
    7y( 7y-9) + 2(7y-9)=0
    (7y-9) ( 7y+2)=0
    y= 9/7, -2/7

    x       y
    5  > 9/7 but
    1/8< 9/7
    So the relation cannot be determined.
