A total of $10,000 was invested for one year. Part of this amount earned simple annual interest at the rate of x percent per year, and the rest earned simple annual interest at the rate of y percent per year. If the total interest earned by the $10,000 for that year was $285, what is the value of x?
(1) x = 12y/11
(2) The ratio of the amount interest earned at the rate of x percent per year to the amount of interest earned at the rate of y percent per year was 8 to 11.
