Since x and y are positive integers, there aren't that many solutions to the equation x + y = 10.
So let's start listing all possible solutions:
x = 1, y = 9 (in which case x - y = -8)
x = 2, y = 8 (in which case x - y = -6)
x = 3, y = 7 (in which case x - y = -4)
At this point, it's obvious that -8 is the smallest possible value of x - y
Answer: E
