Find a and b.

If -4 < x < 0, then a < x/2 < b.
~~~~~~~~~~~~~~~~~~~

You are given the starting inequality

    -4 < x < 0.


Divide all three terms by 2.  You will get

    -2 < x/2 < 0.


Compare it with  a < x/2 < b.


Obviously, you should take  a = -2,  b = 0.


ANSWER.  a = -2;  b = 0.

Solved.
