When positive integer x is divided by 11, the quotient is y and the remainder is 4. When 2x is divided by 6, the quotient is 3y and the remainder is 5. What is the value of 7y – x ?  Choose the correct option:
A) 2 B) 1 C) 0 D) -1 E) -2
(1) x = 11y + 4   (2) 2x = 18y + 5   Let's subtract equation (1) from equation (2).   7y + 1 = x   7y - x = -1   The answer is -1.
