If x is an integer and y = 3x + 2, which of the following CANNOT be a divisor of y?
A) 4
B) 5
C) 6
D) 7
E) 8
Here is what I've been able to understand: since y = non-multiple of 3 + multiple of 3, it will never be divisible by 3. I understand that much. But how do you extend that rationale to "all multiples of 3"?
Pls advise. Thanks.
