let two integers be $\"x\"$ and $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( "if their sum is $\"16\"$ , we have\r
\n" ); document.write( "\n" ); document.write( " $\"x%2By=16\"$ .........solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=16-y\"$ ......eq.1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " and if their difference is $\"-8\"$ , we have\r
\n" ); document.write( "\n" ); document.write( " $\"x-y=-8\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=y-8\"$ ......eq.2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " and if their differences is $\"8\"$ , we have\r
\n" ); document.write( "\n" ); document.write( " $\"x-y=8\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=8%2By\"$ ......eq.3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "from eq.1 and eq.2 we have\r
\n" ); document.write( "\n" ); document.write( " $\"16-y=y-8\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"16%2B8=y%2By\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"24=2y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=12\"$ \r
\n" ); document.write( "\n" ); document.write( "from eq.1 and eq.3 we have\r
\n" ); document.write( "\n" ); document.write( " $\"16-y=y%2B8\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"16-8=y%2By\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"8=2y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=4\"$ \r
\n" ); document.write( "\n" ); document.write( "go to\r
\n" ); document.write( "\n" ); document.write( " $\"x=16-y\"$ ......eq.1, plug in $\"y=12\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=16-12\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=4\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "go to\r
\n" ); document.write( "\n" ); document.write( " $\"x=16-y\"$ ......eq.1, plug in $\"y=4\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=16-4\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=12\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solutions: \r
\n" ); document.write( "\n" ); document.write( " $\"x=4\"$ , $\"y=12\"$ \r
\n" ); document.write( "\n" ); document.write( "or\r
\n" ); document.write( "\n" ); document.write( " $\"x=12\"$ , $\"y=4\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, two integers are: $\"4\"$ and $\"12\"$ \r
