2x^2-y^2=17;;;; 8x^2-4y^2=68
\n" ); document.write( "x^2+4y^2=13;;; x^2+4y^2=13\r
\n" ); document.write( "\n" ); document.write( "Add the two
\n" ); document.write( "9x^2=81
\n" ); document.write( "x^2=9
\n" ); document.write( "x= +/- 3\r
\n" ); document.write( "\n" ); document.write( "y= +/- 1
\n" ); document.write( "18-1=17 in first
\n" ); document.write( "9+4=13 in the second.\r
