It is a system of two linear equations.
\n" ); document.write( "nickels=n
\n" ); document.write( "n+n-4=number of coins=2n-4
\n" ); document.write( ".05n+.10(n-4)=0.80
\n" ); document.write( ".05n+.10n-.40=0.80
\n" ); document.write( ".15n=1.20
\n" ); document.write( "n=8 nickels
\n" ); document.write( "n-4=4 dimes
\n" ); document.write( "That is 40+40=80 cents.
\n" ); document.write( "
\n" );
