Let the two numbers be $\"+a+\"$ and $\"+b+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( "(1) $\"+4a+-+2b+=+-16+\"$
\n" ); document.write( "(2) $\"+a+%2B+b+=+-1+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( "(1) $\"+2a+-+b+=+-8+\"$
\n" ); document.write( "Add (1) and (2)
\n" ); document.write( " $\"+3a+=+-9+\"$
\n" ); document.write( " $\"+a+=+-3+\"$
\n" ); document.write( "and
\n" ); document.write( "(2) $\"+a+%2B+b+=+-1+\"$
\n" ); document.write( "(2) $\"+-3+%2B+b+=+-1+\"$
\n" ); document.write( "(2) $\"+b+=+2+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( "The numbers are -3 and 2
\n" ); document.write( "-------------------------
\n" ); document.write( "check:
\n" ); document.write( "(1) $\"+4%2A%28-3%29+-+2%2A2+=+-16+\"$
\n" ); document.write( "(1) $\"+-12+-4+=+-16+\"$
\n" ); document.write( "(1) $\"+-16+=+-16+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
