Let $\"n\"$ = number of nickels
\n" ); document.write( "Let $\"d\"$ = number of dimes
\n" ); document.write( " $\"n+%2B+d+=+55\"$
\n" ); document.write( " $\"d+=+55+-+n\"$
\n" ); document.write( " $\"5n+%2B+10d+=+450\"$
\n" ); document.write( " $\"5n+%2B+10%2855+-+n%29+=+450\"$
\n" ); document.write( " $\"5n+%2B+550+-+10n+=+450\"$
\n" ); document.write( " $\"-5n+=+-100\"$
\n" ); document.write( " $\"n+=+20\"$
\n" ); document.write( " $\"d+=+55+-+n\"$
\n" ); document.write( " $\"d+=+35\"$
\n" ); document.write( "There are 20 nickels and 35 dimes
\n" ); document.write( "check:
\n" ); document.write( " $\"5n+%2B+10d+=+450\"$
\n" ); document.write( " $\"5%2A20+%2B+10%2A35+=+450\"$
\n" ); document.write( " $\"100+%2B+350+=+450\"$
\n" ); document.write( " $\"450+=+450\"$
\n" ); document.write( "OK \n" ); document.write( "
