If you sub for x and y, you'll find that it's correct.
\n" ); document.write( "---------
\n" ); document.write( "x+y=1
\n" ); document.write( "3 - 2 = 1
\n" ); document.write( "------------
\n" ); document.write( "x-7y=17
\n" ); document.write( "3 - 7(-2) = 17
\n" ); document.write( "
\n" ); document.write( "
\n" );
