Call the number of nickels and quarters, n and q.
\n" ); document.write( "Thus we have
\n" ); document.write( "n + q = 69
\n" ); document.write( "The value equation is
\n" ); document.write( "5n + 25q = 1245 (we work in cents)
\n" ); document.write( "Now multiply the top equation by five and subtract and we get
\n" ); document.write( "5n + 25q = 1245
\n" ); document.write( "-(5n + 5q = 345)
\n" ); document.write( "----------------
\n" ); document.write( "20q = 900
\n" ); document.write( "q = 45 quarters so that we have
\n" ); document.write( "n = 69-45 = 24 nickels
\n" ); document.write( "
\n" );
