when positive integer x is divided by 12 , the quotient is y and the remainder is 3 . when 2 x is divided by 11 , the quotient is 3 y and the remainder is 6 . what is the value of 21 y – x ?
"( 1 ) x = 12 y + 3 ( 2 ) 2 x = 33 y + 6 ( 2 ) - ( 1 ) : x = 21 y + 3 21 y - x = - 3 the answer is e ."
subtract(multiply(21, divide(subtract(multiply(2, 3), 6), subtract(multiply(11, 3), multiply(2, 12)))), add(multiply(12, divide(subtract(multiply(2, 3), 6), subtract(multiply(11, 3), multiply(2, 12)))), 3))
