If for integer x, 5 < x < 10 and y = x + 5. What is the greatest possible value of x + y ?

If for integer x, 5 < x < 10 and y = x + 5. What is the greatest possible value of x + y ? Correct Answer 23

Since y = x + 5y = x + 5 then x + y = x + (x + 5) = 2x + 5x + y = x + (x + 5) = 2x + 5. So, we need to find the greatest possible integer value of 2x + 52x + 5. Multiply 5
