Answer:
The required inequality for both the statement is:
and 
The solution for the inequalities are x>-6 and
respectively.
Step-by-step explanation:
Consider the provided information.
One half a number increased by three is greater than zero
Let the number is x.
Thus, the required inequality is:
Or One half a number increased by three is less than or equal to negative three.
Thus, the required inequality is:

Now solve the above inequality for x.
or 
or 
or 
or 
Hence, the value of x is
or
