Given positive integer x, which of the following CANNOT be evenly divisible by x?
Choose the correct choice from the following answers.
A) 7x	B) x + 2	C) 2x - 1/2	D) 3x − 1	E) x + 6
This can be easily solved by substituting values:   Assume x to be 1   A. 7x: 7 is evenly divisible by 1   B. x + 2: 3 is evenly divisible by 1   C. 2x - 1/2: 3/2 is not evenly divisible by 1   D. 3x − 1: 2 is evenly divisible by 1   E. x + 6: 7 is not evenly divisible by 1   Option 2x - 1/2
