Let &lt;b&gt;&lt;i&gt;x&lt;/i&gt;&lt;/b&gt; represent Lee&#39;s age now.  Then Phil is &lt;b&gt;&lt;i&gt;x&lt;/i&gt; - 7&lt;/b&gt; now.  Lee&#39;s age 11 years ago:  &lt;b&gt;&lt;i&gt;x&lt;/i&gt; - 11&lt;/b&gt; and Phil&#39;s age 11 years ago: &lt;b&gt;&lt;i&gt;x&lt;/i&gt; - 7 - 11&lt;/b&gt; = &lt;b&gt;&lt;i&gt;x&lt;/i&gt; - 18&lt;/b&gt;, so:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x - 11 = 2(x - 18)]


Solve for &lt;b&gt;&lt;i&gt;x&lt;/i&gt;&lt;/b&gt; to get Lee&#39;s age.
