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 1. What is the value of 7y – x ?
Pick one:
A) 1
B) 2
C) 3
D) 4
E) 5
(1) x = 11y + 4   (2) 2x = 18y + 1   Let's subtract equation (1) from equation (2).   7y - 3 = x   7y - x = 3   The answer is 3.
