&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;P:1792 (Monica Dragoș)&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;

&amp;#039;&amp;#039;Determinați numărul natural &amp;lt;math&amp;gt;\overline{ab}&amp;lt;/math&amp;gt; pentru care &amp;lt;math&amp;gt;a \times \overline{b00b} + \overline{aa} = 2024&amp;lt;/math&amp;gt;.&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Soluție&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
Evident, cifrele &amp;lt;math&amp;gt;a&amp;lt;/math&amp;gt; și &amp;lt;math&amp;gt;b&amp;lt;/math&amp;gt; sunt diferite de &amp;lt;math&amp;gt;0&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Din &amp;lt;math&amp;gt;\overline{b00b} &amp;lt; 2024&amp;lt;/math&amp;gt; se obține &amp;lt;math&amp;gt;b\le2&amp;lt;/math&amp;gt;, deci cifra &amp;lt;math&amp;gt;b&amp;lt;/math&amp;gt; poate lua valorile &amp;lt;math&amp;gt;1&amp;lt;/math&amp;gt; sau &amp;lt;math&amp;gt;2&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Egalitatea din enunț se poate scrie în forma echivalentă &amp;lt;math&amp;gt;a \times b \times 1001 + a \times 11 =2024&amp;lt;/math&amp;gt;. Cum &amp;lt;math&amp;gt;1001 = 11 \times 91&amp;lt;/math&amp;gt; și &amp;lt;math&amp;gt;2024 = 11 \times 184&amp;lt;/math&amp;gt;, fiecare termen se împarte cu &amp;lt;math&amp;gt;11&amp;lt;/math&amp;gt; și se obține &amp;lt;math&amp;gt;a \times b \times 91 + a = 184&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Pentru &amp;lt;math&amp;gt;b=1&amp;lt;/math&amp;gt;, egalitatea de mai sus devine &amp;lt;math&amp;gt;91 \times a +  a = 184&amp;lt;/math&amp;gt;, ceea ce conduce la &amp;lt;math&amp;gt;92 \times a = 184&amp;lt;/math&amp;gt;, ecuație ce are soluția &amp;lt;math&amp;gt;a=2&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Pentru &amp;lt;math&amp;gt;b=2&amp;lt;/math&amp;gt;, egalitatea de mai sus devine &amp;lt;math&amp;gt;182 \times a +  a = 184&amp;lt;/math&amp;gt;, ceea ce conduce la egalitatea &amp;lt;math&amp;gt;183 \times a = 184&amp;lt;/math&amp;gt;  pentru care nu există &amp;lt;math&amp;gt;a&amp;lt;/math&amp;gt; număr natural care să o satisfacă.&lt;/div&gt;</summary>
