The second side of a triangular deck is 6 feet longer than the shortest​ side, and the third side is 6 feet shorter than twice the length of the shortest side. If the perimeter of the deck is 48 ​feet, what are the lengths of the three​ sides?

x=shortest side length

x+x+6+2x-6=4x=48

x=12 second side=18 third side =18
