Graph the lines,
\n" ); document.write( "\"7x%2B2y=3\"
\n" ); document.write( "\"7x%2B2y=-3\"
\n" ); document.write( "\"y-x=4\"
\n" ); document.write( "\"y-x=-4\"
\n" ); document.write( "Look for the intersection points.
\n" ); document.write( "The one with the maximum value will be the one that is most to the right and most above the x-axis.
\n" ); document.write( "In this case,
\n" ); document.write( "\"x%2By=-0.556%2B3.444=2.888\"
