See, in a parallelogram, two sides facing each other are always equal and they are always parallel. If ABCD is the quadrilateral (parallelogram) then http://www.kidsmathgamesonline.com/images/pictures/shapes/parallelogram.jpg The sides facing each other (parallel sides) will have to be equal. Therefore if AB = 3y-6, and CD = 2y + 4, then they have to be equal, just equate it. http://www.kidsmathgamesonline.com/images/pictures/shapes/parallelogram.jpg Look at the images for reference :)
