I don't know how to start this prove. For a group, it's easy to prove. Like we can start with Let e be an identity element. Suppose a belongs to G(where G is a group) and b,b' belongs to G are the inverse of the element a. now ae=ea=b and ae=ea=b' But I don't know how to start for semigroup.

The fact that $b$ is the inverse of $a$ means $$ ab=ba=e $$ and not that $ae=ea=b$.
If $b'$ is another inverse of $a$, then $$ b'=eb'=(ba)b' $$ Now continue using associativity.
