A chemist has two acid solutions, one that contains 14.0% acid and another with 27.0% acid. How many litres of each must be mixed to make 250 litres of solution containing 17.64% acid?

\(x\) = acid 1
\(y\) = acid 2

formula relating volume of solutions: \(x + y = 250\)
formula relating volume of acid only: \(0.14x + 0.27y = 250 (0.1764)\)
