Statement 2 states that x is not evenly divisible by an odd number other than 1. It talks, IMO, about numbers such as 2, 4, 8, 10 etc i.e. multiples of 2 that are not divisible by ANY odd number but 1. _________________

10 is divisible by 5 so x cannot be 10.

Is x a prime number?

(1) x is an even number. If x=2 then the answer is YES but if x is any other even number then the answer is NO. Not sufficient.

(2) x can not be divided evenly by an odd number other than 1. This statement implies that x is some power of 2: 2, 4, 8, 16, ... Not sufficient.

(1)+(2) Still not sufficient. Consider x=2 and x=4.

This is more of a "don't overthink too much question" than anything else. is x prime?

(1) x is even. X could be 2, hence prime. But also 4,6,8,...IS (2) x can not be divided evenly by an odd number other than 1. This is tempting but the statement says nothing about even numbers. So x could be even! (I see what you did there).

Together it basically stays the same. From (2), x could be be even and from (1) we only get that x is even, hence still IS.
