Let the numbers be $\"+x+\"$ and $\"+y+\"$
\n" ); document.write( "given:
\n" ); document.write( " $\"+x+%2B+y+=+619+\"$
\n" ); document.write( " $\"+x+-+y+=+33+\"$ Add the equations
\n" ); document.write( "-------------
\n" ); document.write( " $\"+2x+=+652+\"$
\n" ); document.write( " $\"+x+=+326+\"$
\n" ); document.write( "and, since
\n" ); document.write( " $\"+x+-+y+=+33+\"$
\n" ); document.write( " $\"+326+-+y+=+33+\"$
\n" ); document.write( " $\"+y+=+326+-+33+\"$
\n" ); document.write( " $\"+y+=+293+\"$
\n" ); document.write( "The numbers are 293 and 326
\n" ); document.write( "check:
\n" ); document.write( " $\"+x+%2B+y+=+619+\"$
\n" ); document.write( " $\"+326+%2B+293+=+619+\"$
\n" ); document.write( " $\"+619+=+619+\"$
\n" ); document.write( "OK\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
