if 5 < x < 11 and y = x + 6 , what is the greatest possible integer value of x + y ?
"x + y = x + x + 6 = 2 x + 6 we need to maximize this value and it needs to be an integer . 2 x is an integer when the decimal of x is . 0 or . 5 the largest such value is 10.5 then x + y = 10.5 + 16.5 = 27 . the answer is c ."
add(add(6, const_10), const_10)
