Let $\"n\"$ = number of nickels she has
\n" ); document.write( "Let $\"d\"$ = number of dimes she has
\n" ); document.write( "given:
\n" ); document.write( " $\"+d+=+5n+\"$
\n" ); document.write( " $\"+10d+%2B+5n+=+330+\"$ (in cents)
\n" ); document.write( "------------------
\n" ); document.write( "Use substitution
\n" ); document.write( " $\"10%2A5n+%2B+5n+=+330+\"$
\n" ); document.write( " $\"+50n+%2B+5n+=+330+\"$
\n" ); document.write( " $\"+55n+=+330+\"$
\n" ); document.write( " $\"+5n+=+30+\"$
\n" ); document.write( " $\"+n+=+6+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"d+=+5n\"$
\n" ); document.write( " $\"+d+=+5%2A6\"$
\n" ); document.write( " $\"d+=+30\"$
\n" ); document.write( "She has 6 nickels and 30 dimes \n" ); document.write( "
