Question 1207777
<pre>

{{{system(xy=-8,x+y=-2)}}}

Solve one of the equations for either x or y.  Then substitute
what you get in the other equation.  You will get a quadratic 
equation that will factor.  It will have two solutions, although
the x-value of one will be the y-value of the other.  Find the
other value by substituting.
