  1. Can't tell whether A is in between B and E or not.

    But, you know that BEC=BED

    That should help you pin down AEC.

    If A is between B and C

    BEA+AEC=BEC
    11x-12 + AEC = 4x+1
    AEC = 13-7x

    or, if B is between A and C,

    AEC-AEB=BEC
    AEC-11x+12 = 4x+1
    AEC = 15x-13

    Of course, A could be a lot of other places, too.
