    5x = 2x + 1

    3x = 1

    x = 1/3

    The figure will be a parallelogram if the diagonals bisect one another.  Therefore, if BE is congruent to DE then it will be a parallelogram:

    5x = 2x + 1

    3x = 1

    x = 1/3

    the diagonals of a parallelogram bisect each other. so

    2x + 1 = 5x

    3x = 1

    x = 1/3
