\n" ); document.write( "\n" ); document.write( "x+7 = y+7+14
\n" ); document.write( "x-y = 14 -----------1\r
\n" ); document.write( "\n" ); document.write( "last year\r
\n" ); document.write( "\n" ); document.write( "x-1+y-1=20
\n" ); document.write( "x+y = 22 ----------2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1+2 => 2x = 36\r
