Answer 2

Answer: - 6 or 6

Step-by-step explanation:

Possible values of x and y:

x; y

1 * 16 = 16

2 * 8 = 16 (Suits us because x + y would be 10 only in this case)

4 * 4 = 16

Thus, we can conclude that x is 2 or 8, and y is 8 or 2 respectively.

Hence,

x - y = 8 - 2 or 2 - 8 = 6 or -6

Hope it helps!
