\n" ); document.write( "\n" ); document.write( "10*x+5*(53-x)=4.05*100
\n" ); document.write( "10x+265-5x=405
\n" ); document.write( " 5x=405-265
\n" ); document.write( "5x=140
\n" ); document.write( "5x/5=140/5
\n" ); document.write( "x=28\r
\n" ); document.write( "\n" ); document.write( "Dimes=x=28
\n" ); document.write( "Nickels=53-x=53-28=25\r
