Twice a number is greater than or equal to negative 5, what are the possible values of the number?
~~~~~~~~~~~~~~~ 

Let x be the number to find.


The problem says

    2x >= -5.


Divide both sides by 2.  You will get an EQUIVALENT inequality then

    x >= -5/2

    x >= -2.5.


It is your ANSWER :  x >= - 2.5.


For example, x can be -2, -1.5, -1, etc.


But x can not be -3, -4, etc.

Solved.
