Hi...☺Here is your answer...✌GIVEN THAT,3x - 2Y = 11 -----(1)xy = 12 -----(2)Cubing both sides in eq(1)We get(3x - 2y)³ = 11³(3x)³ - (2y)³ - 3(3x)(2y) (3x - 2y) = 11³27x³ - 8y³ - 18xy × 11 = 11³ __ [from (1)]27x³ - 8y³ - 18×12×11 = 11³ __ [from(2)]27x³ - 8y³ = 11³ + 18×12×11= 11 (11² + 18×12)= 11 (121 + 216)= 11 × 337= 3707Hence,27x³ - 8y³ = 3707
