Instead of doing your homework for you, I'll do another one exactly like it step\r\n" );
document.write( "by step.
A collection of nickels and dimes makes $2.10. How many of each
\n" ); document.write( "coin are there if there are three times as many dimes as nickels?
\r\n" );
document.write( "0.05N + 0.10D = 2.10\r\n" );
document.write( "            D = 3N\r\n" );
document.write( "\r\n" );
document.write( "Substitute 3N for D in 0.05N + 0.10D = 2.10\r\n" );
document.write( "\r\n" );
document.write( "0.05N + 0.10(3N) = 2.10\r\n" );
document.write( "   0.05N + 0.30N = 2.10\r\n" );
document.write( "           0.35N = 2.10\r\n" );
document.write( "               N = 2.10/0.35\r\n" );
document.write( "               N = 6\r\n" );
document.write( "\r\n" );
document.write( "Substitute 6 for N in D = 3N\r\n" );
document.write( "\r\n" );
document.write( "D = 3(6)\r\n" );
document.write( "D = 18\r\n" );
document.write( "\r\n" );
document.write( "Answer: 6 nickels and 18 dimes\r\n" );
