Let x be the number of nickels.
\n" ); document.write( "Then (77-x) is the number of dimes.\r
\n" ); document.write( "\n" ); document.write( " $\"0.05x+%2B+%280.1%29%2877-x%29+=+6.1\"$
\n" ); document.write( " $\"0.05x+%2B+7.7+-+0.1x+=+6.1\"$
\n" ); document.write( " $\"0.05x+%2B+7.7+-+0.1x+=+6.1\"$
\n" ); document.write( " $\"-0.05x+=+-1.6\"$
\n" ); document.write( " $\"x+=+32\"$ \r
\n" ); document.write( "\n" ); document.write( "∴ Marcus has 32 nickels and (77-32=45) dimes. \n" ); document.write( "
