<PRE><B>Question 174931</B>
Find {{{matrix(1,3, &quot;g(&quot;,9,&quot;)&quot;)}}} given that {{{matrix(1,5, &quot;g(&quot;,x,&quot;)&quot;,&quot;=&quot;,2x+3)}}}
&lt;pre&gt;&lt;font size = 4 color = &quot;indigo&quot;&gt;&lt;b&gt;
Substitute 9 for all the x&#39;s&quot;

{{{matrix(1,5, &quot;g(&quot;,9,&quot;)&quot;,&quot;=&quot;,2(9)+3)}}}

Simplify the right side:

{{{matrix(1,5, &quot;g(&quot;,9,&quot;)&quot;,&quot;=&quot;,18+3)}}}

{{{matrix(1,5, &quot;g(&quot;,9,&quot;)&quot;,&quot;=&quot;,21)}}}

Easy, wasn&#39;t it?
