when positive integer x is divided by 10 , the quotient is y and the remainder is 3 . when 2 x is divided by 7 , the quotient is 3 y and the remainder is 1 . what is the value of 11 y – x ?
"( 1 ) x = 10 y + 3 ( 2 ) 2 x = 21 y + 1 ( 2 ) - ( 1 ) : x = 11 y - 2 11 y - x = 2 the answer is a ."
subtract(multiply(11, divide(subtract(multiply(2, 3), 1), subtract(multiply(7, 3), multiply(2, 10)))), add(multiply(10, divide(subtract(multiply(2, 3), 1), subtract(multiply(7, 3), multiply(2, 10)))), 3))
