The diagnonals of a parallelogram bisect each other ,
so
=》 BD = 3x × 2
=》BD = 6x
and there's given that
=》

=》

=》

=》

so, if x = 4 , then the given quadrilateral is a parallelogram.
They can both be divided by 2, so you would divide 4 by 2 which is 2 and then 6 by 2 which is 3. it simplifies to 2/3
Answer:
The answer would be x=8/3
