First thing, I'm assuming you have wallpaper that's been saved
to do the repair with and that you've looked at it vs the existing
and it matches. The big problem here is that wallpaper ages and
the old and new may not match well enough.
If it matches, I'd use a steamer to loosen the section.
Then I'd let it mostly dry. Then cut a section of the new
that an inch or so longer than the bad section. Lay it over
the old, secure it with some tape, then use a razor and
straightedge to cut through both new and old at the same
time. Then remove the cut off section of the old and
the new piece will mate with the cut off ends of the old.
I would do this across a full width, do two widths if necessary,
instead of having a vertical cut instead of a normal seam.
