Let x and y be the 2 numbers \r
\n" ); document.write( "\n" ); document.write( "then we have \r
\n" ); document.write( "\n" ); document.write( "x + y =33 ........(1) (Sum is 33 )
\n" ); document.write( "and
\n" ); document.write( "x - y =9 ........(2) (difference is 9 )\r
\n" ); document.write( "\n" ); document.write( "adding 1 and 2 \r
\n" ); document.write( "\n" ); document.write( "2x = 42
\n" ); document.write( "x= 21\r
\n" ); document.write( "\n" ); document.write( "Substituting the value of x in 1
\n" ); document.write( "21 + y = 33
\n" ); document.write( "y = 33-21
\n" ); document.write( "y= 12\r
\n" ); document.write( "\n" ); document.write( "Numbers are 21 and 12
\n" ); document.write( "
