Question 675418
Two times an unknown number is at least 4, and 8 more than the number exceeds 5. Find all possible values for the unknown number.
<pre>
Let n be the number.
</pre>
>>Two times an unknown number is at least 4<<
<pre>
2n &#8805; 4 
 n &#8805; 2
</pre>
8 more than the number exceeds 5
<pre>
n+8 > 5
  n > -3

So if n &#8805; 2, it's certainly > -3, so any number 2 
or greater satisfies that.
