We will want an equation for the NUMBER of coins. d+n=65
\n" ); document.write( "We will also want an equation for the VALUE of coins. .10d+.05n=5.35
\n" ); document.write( ".10d+.05n=5.35
\n" ); document.write( "d+n=65
\n" ); document.write( "Let's get rid of decimals.
\n" ); document.write( "10d+5n=535
\n" ); document.write( "d+n=65
\n" ); document.write( "multiply by 5\r
\n" ); document.write( "\n" ); document.write( "5d+5n=65*5
\n" ); document.write( "10d+5n=535
\n" ); document.write( "5d+5n=325
\n" ); document.write( "subtract
\n" ); document.write( "5d=535-325=210
\n" ); document.write( "d=210/5=42
\n" ); document.write( "d+n=65
\n" ); document.write( "42+n=65
\n" ); document.write( "n=23
\n" ); document.write( "check
\n" ); document.write( "10d+5n=535
\n" ); document.write( "10*42+5*23=535
\n" ); document.write( "ok\r
