x+y=621
\n" ); document.write( "x-y=109 now add.
\n" ); document.write( "---------
\n" ); document.write( "2x=730
\n" ); document.write( "x=730/2
\n" ); document.write( "x=365 ans.
\n" ); document.write( "365+y=621
\n" ); document.write( "y=621-365
\n" ); document.write( "y=256 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "365-256=109
\n" ); document.write( "109=109
\n" ); document.write( "
