You can either do this:

echo "<a href=\"news-delete.php?id=".$article['id']."&amp;x=".$x."\">Delete</a>";

...which can get very messy. Or, what I prefer, is to exit out of the PHP when doing HTML, like so:

?>

<a href="news-delete.php?id=<?php echo $article['id']; ?>&amp;x=<?php echo $x; ?>">Delete</a>

<?php
