If 2x + 6y = 3 and 3x -7y =6 then it has to be 6y x 7y =13
Y=d-3. Y is equal to the cost of the sweaters before the price was raised. D represents the price of the sweaters after the price jump. The three is how much the sweater price was raised by. Say the new price of the sweaters are $29.99 each. You would plug in 29.99 for d. y=29.99-3. The new price of the sweaters would be $26.99 (this is just a sample problem)
