$\"d\"$ = number of dimes
\n" ); document.write( " $\"q\"$ = number of quarters
\n" ); document.write( "given:
\n" ); document.write( " $\"d+%2B+q+=+27\"$
\n" ); document.write( " $\"d+=+q+-+17\"$
\n" ); document.write( "------------
\n" ); document.write( "By substitution:
\n" ); document.write( " $\"q+-+17+%2B+q+=+27\"$
\n" ); document.write( " $\"2q+=+44\"$
\n" ); document.write( " $\"q+=+22\"$
\n" ); document.write( "and, since
\n" ); document.write( " $\"d+%2B+q+=+27\"$
\n" ); document.write( " $\"d+=+27+-+22\"$
\n" ); document.write( " $\"d+=+5\"$
