Call the numbers $\"a\"$ and $\"b\"$
\n" ); document.write( "given:
\n" ); document.write( " $\"a+%2B+b+=+12\"$
\n" ); document.write( " $\"b+-+a+=+-2\"$
\n" ); document.write( "Add these equations:
\n" ); document.write( " $\"a+%2B+b+=+12\"$
\n" ); document.write( " $\"-a+%2B+b+=+-2\"$
\n" ); document.write( " $\"2b+=+10\"$
\n" ); document.write( " $\"b+=+5\"$
\n" ); document.write( "and,
\n" ); document.write( " $\"5+-+a+=+-2\"$
\n" ); document.write( " $\"-a+=+-7\"$
\n" ); document.write( " $\"a+=+7\"$
\n" ); document.write( "The numbers are 7 and 5 \n" ); document.write( "
