A total of \(\$60,000\) 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 \(\$60,000\) for that year was \(\$4,080,\) what is the value of \(x?\)

(1) \(x = \dfrac{3y}4\)
(2) The ratio of the amount that earned interest at the rate of \(x\) percent per year to the amount that earned interest at the rate of \(y\) percent per year was \(3\) to \(2.\)
