    x = 4 (again assuming that the quadrilateral is a parallelogram as it appears to be visually).

    i do not know what the shape of the quadrilateral is it does seem "to scale" more information is needed

    How can x be negative????????? It is length for god's sake.

    Please don't argue this point on this particular problem. This problem is giving x as a variable representing length. It can't be negative.

    if we assume it's a parallelogram then 3x=12 and 8= 2x it has to satisfy the other equation also 3x+12=8+2x can't be satisfied simultaneously

    Why does 3x+12 = 8 + 2x??? Who said the diagonals of the parallelogram are equal???

    Whoops. You are right. 8=2x AND 3x=12

    Thank you! It is not my purpose to prove I am right. But, to not confuse the person asking the question.
