Answer: the cost of the couch is 664 and the cost of the coffe table is 332
Explanation:
X is the cost of the coffee table and 2x is the cost of the couch (which is two times more than the coffee table)
2x + x = $996
3x = $996
x = 996/ 3
x = $332 (this is what the coffee table cost)
2x => 2(332)
2x => $664 (the cost of the couch which is two times the cost of the coffee table)
together, $332 + $664 = $996 total
