two numbers are in the ratio of 5 : 7 . if 12 is subtracted from each number , they are in the ratio of 11 : 17 . what are the two numbers ?
"( 5 x - 12 ) : ( 7 x - 12 ) = 11 y : 17 y 5 x - 12 = 11 y 7 x - 12 = 17 y 84 - 60 = 85 y - 77 y 24 = 8 y y = 3 5 x - 12 = 33 x = 9 the two numbers are 5 x and 7 x which are 45 and 63 . the answer is a ."
subtract(multiply(multiply(subtract(multiply(17, 12), multiply(11, 12)), 5), divide(7, 5)), multiply(subtract(multiply(17, 12), multiply(11, 12)), 5))
