If xyz represents a positive three-digit number, where x, y and z are one-digit integers, which of the following CANNOT be true? Choose the correct option
A) y – x - z = 9 B) x – y - z = 9 C) x + y + z = 9 D) xyz = 9 E) x/y/z = 9
The (hundreds place digit, x) cannot be zero, but (tens and ones place digits; y and z) can be zero.   y – x - z = 9 is NOT possible   B is possible   C is possible   D is possible   E is possible   y – x - z = 9nswer: y – x - z = 9
