two numbers are in the ratio of 5 : 7 . if 7 is subtracted from each number , they are in the ratio of 2 : 3 . what are the two numbers ?
"( 5 x - 7 ) : ( 7 x - 7 ) = 2 y : 3 y 5 x - 7 = 2 y 7 x - 7 = 3 y 49 - 35 = 15 y - 14 y 14 = y 5 x - 7 = 28 x = 7 the two numbers are 5 x and 7 x which are 35 and 49 . the answer is a ."
subtract(multiply(multiply(subtract(multiply(3, 7), multiply(2, 7)), 5), divide(7, 5)), multiply(subtract(multiply(3, 7), multiply(2, 7)), 5))
