length = x, width = y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + y = 23
\n" ); document.write( "x - y = 13\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Add both equations to get 2x = 36 ---> x = 18. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "18 + y = 23
\n" ); document.write( "y = 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "area = xy = (18)(5) = 90 unit^2
\n" ); document.write( "
\n" );
