\n" ); document.write( ":
\n" ); document.write( "n+d=8..........eq 1
\n" ); document.write( ".05n+.1d=.55...eq 2
\n" ); document.write( ":
\n" ); document.write( "lets re write eq 1 to n=8-d and take that value and plug it into eq 2
\n" ); document.write( ":
\n" ); document.write( ".05(8-d)+.1d=.55
\n" ); document.write( ":
\n" ); document.write( ".4-.05d+.1d=.55
\n" ); document.write( ":
\n" ); document.write( ".05d=.15
\n" ); document.write( ":
\n" ); document.write( " $\"highlight%28d=3%29\"$ dimes
\n" ); document.write( ":
