\n" ); document.write( "(1) $\"+5n+%2B+10d+=+360+\"$ ( in cents )
\n" ); document.write( "(2) $\"+d+=+n+%2B+1+\"$
\n" ); document.write( "----------------
\n" ); document.write( "(2) $\"+n+=+d+-+1+\"$
\n" ); document.write( "Substitute (2) into (1)
\n" ); document.write( "(1) $\"+5%2A%28+d+-+1+%29+%2B+10d+=+360+\"$
\n" ); document.write( "(1) $\"+5d+-+5+%2B+10d+=+360+\"$
\n" ); document.write( "(1) $\"+15d+=+365+\"$
\n" ); document.write( "(1) $\"+d+=+24.333+\"$
