Let the number of $5 bills = x
\n" ); document.write( "And the number of $10 bills = y
\n" ); document.write( "Total nomber of bills x+y = 12 ...(1)
\n" ); document.write( "Total value is 5x+10y = 100 ...(2)
\n" ); document.write( "(1)*5=> 5x+5y = 60 ...(3)
\n" ); document.write( "(2)-(3)=> 5y=40
\n" ); document.write( " y= 40/5
\n" ); document.write( " y= 8
\n" ); document.write( "(1)=> x+8=12
\n" ); document.write( "x=12-8
\n" ); document.write( "x=4
\n" ); document.write( "So, the number of $5 bills = 4
\n" ); document.write( "And the number of $10 bills = 8
\n" ); document.write( "
\n" );
