It seems like 4X , 3(x + 6) are diagonal of the quadrilateral , in order for the quadrilateral be parallelogram
has to be equal length.

In which case solution of Patricia S . is the answer. Otherwise the problem doesn't make any sense whatsoever.

Victoria,

Are the 4x and 3(x+6) on opposite sides of the quadrilateral? If so, you can solve for x by setting them equal to each other (opposite sides of a parallelogram have equal lengths).  It would look like this:

4x = 3(x+6)
4x = 3x+18
x = 18

Good luck!
