.
Equation, &amp;nbsp;which is translation to the condition, &amp;nbsp;is &amp;nbsp;d).



&lt;U&gt;BUT there is &amp;nbsp;NO &amp;nbsp;such integer x which satisfies equation &amp;nbsp;d)&lt;/U&gt;.



&lt;U&gt;It does not exist&lt;/U&gt;.



So, &amp;nbsp;the problem is, &amp;nbsp;actually, &amp;nbsp;self-contradictory.



In other words, &amp;nbsp;the problem is &amp;nbsp;&lt;U&gt;fake&lt;/U&gt;  &amp;nbsp;and  is &amp;nbsp;&lt;U&gt;DEFECTIVE&lt;/U&gt;.
