Let the numbers be \"a\" and \"b\". \"b\" is the larger
\n" ); document.write( "\"a+%2B+b+=+15\"
\n" ); document.write( "\"2a+%2B+b+=+-1\"
\n" ); document.write( "Subtract the 2nd from the 1st
\n" ); document.write( "\"-a+=+16\"
\n" ); document.write( "\"a+=+-16\"
\n" ); document.write( "\"-16+%2B+b+=+15\"
\n" ); document.write( "\"b+=+31\"
\n" ); document.write( "The numbers are -16 and 31
\n" ); document.write( "check:
\n" ); document.write( "\"-16+%2B+31+=+15\"
\n" ); document.write( "\"15+=+15\"
\n" ); document.write( "\"2a+%2B+b+=+-1\"
\n" ); document.write( "\"2%2A%28-16%29+%2B+31+=+-1\"
\n" ); document.write( "\"-32+%2B+31+=+-1\"
\n" ); document.write( "OK
