<PRE><B>Question 1103604</B>
&lt;pre&gt;
{{{system(matrix(2,6,

x,&quot;&quot;+&quot;&quot;,y,&quot;&quot;,&quot;&quot;=&quot;&quot;,65,
x,&quot;&quot;-&quot;&quot;,y,&quot;&quot;,&quot;&quot;=&quot;&quot;,13))}}}

Add the two equations term by term and get:

{{{matrix(2,5,

2x,&quot;&quot;,&quot;&quot;=&quot;&quot;,&quot;&quot;,78,
 x,&quot;&quot;,&quot;&quot;=&quot;&quot;,&quot;&quot;,39)}}}

You finish by substituting 39 for x in one of the equation
to find y.
