First we start with the value of coins equation:
\n" ); document.write( "(i) 5N + 10D = 100
\n" ); document.write( "Second, we have the number of coins equation:
\n" ); document.write( "(ii) D = 2N
\n" ); document.write( "By substitution, we get
\n" ); document.write( "(iii) 5N + 10(2N) = 100
\n" ); document.write( "solving for N, we get
\n" ); document.write( "25N = 100
\n" ); document.write( "N = 4
\n" ); document.write( "This means that D =8.
