x+y=123 or x=123-y
\n" ); document.write( "x-y=45
\n" ); document.write( "123-y-y=45
\n" ); document.write( "-2y=45-123
\n" ); document.write( "-2y=-78
\n" ); document.write( "y=-78/-2
\n" ); document.write( "y=39 ans. for the smaller number.
\n" ); document.write( "x=123-39
\n" ); document.write( "x=84 ans. for the larger number.
\n" ); document.write( "Proof:
\n" ); document.write( "84-39=45
\n" ); document.write( "45=45 \n" ); document.write( "
