Given positive integer X, which of the following CAN NOT be evenly divisible by X?
Select
A) x + 4  B) x+ 7  C) 2x + 1  D) x − 1  E) x + 1⁄2
This can be easily solved by substituting values:   Assume x to be 1   A. x + 4: 5 is evenly divisible by 1   B. x + 7: 8 is evenly divisible by 1   C. 2x + 1: 3 is evenly divisible by 1   D. x − 1: 0 is evenly divisible by 1   E. x + 1⁄2: 3/2 is not evenly divisible by 1   Option x + 1⁄2
