Equations with Solution Sets

At a local movie theater, the price for tickets is $10.00 for adults and $5.50 for students. The price of adult tickets increases by $0.20 each year, and the price of student tickets increases by $0.50 each year. The equations y = 0.20x + 10 and y = 0.50x + 5.5 represent the situation, where x represents the number of years since the first year, and y represents the price of the tickets. After how many years will the ticket prices be the same?
