Let x = the first number
\n" ); document.write( " y = the second number\r
\n" ); document.write( "\n" ); document.write( "The sum of two numbers is 75.
\n" ); document.write( "x+y=75\r
\n" ); document.write( "\n" ); document.write( "The difference between those numbers is 21.
\n" ); document.write( "x-y=21\r
\n" ); document.write( "\n" ); document.write( "x+y=75
\n" ); document.write( "x-y=21
\n" ); document.write( " 2x=96
\n" ); document.write( " x=48\r
\n" ); document.write( "\n" ); document.write( "Substitute x with 48
\n" ); document.write( "48+y=75
\n" ); document.write( " y=75-48
\n" ); document.write( " y=27\r
\n" ); document.write( "\n" ); document.write( "The numbers are 27 and 48.\r
\n" ); document.write( "\n" ); document.write( "Check
\n" ); document.write( "48-27 = 21
\n" ); document.write( " 21 = 21\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
