nickels=x
\n" ); document.write( "dimes=y
\n" ); document.write( "x+y=70
\n" ); document.write( ".05x+.10y=5.70
\n" ); document.write( "5x+10y=570, multiplying by 100.
\n" ); document.write( "-5x-5y=-350, multiplying the first by -5
\n" ); document.write( "5y=220
\n" ); document.write( "y=44 dimes, $4.40
\n" ); document.write( "x=26 nickels, $1.30
\n" ); document.write( "
\n" );
