Let $\"d\"$ = number of dimes
\n" ); document.write( "Let $\"n\"$ = number of nickels
\n" ); document.write( "given:
\n" ); document.write( " $\"n+=+5d\"$
\n" ); document.write( " $\"5n+%2B+10d+=+105\"$ (in cents)
\n" ); document.write( "------------
\n" ); document.write( "By substitution:
\n" ); document.write( " $\"5d+%2B+10d+=+105\"$
\n" ); document.write( " $\"15d+=+105\"$
\n" ); document.write( " $\"d+=+7\"$
\n" ); document.write( "and, since
\n" ); document.write( " $\"n+=+5d\"$
\n" ); document.write( " $\"n+=+35\"$
\n" ); document.write( "She has 35 nickels and 7 dimes
\n" ); document.write( " \n" ); document.write( "
