Class 2 towing?

Crossroads:
The one that puzzles me is C1+E with weight limit 107.
I understand that means 8250 kg max combined weight, but if the PM MAM is < 7500 kg, can you pull a trailer over 750 kg?
(Makes a big difference for anyone wanting to tow a car behind a motorhome).

I gave up trying to interpret it and I’m doing C+E next month, but it would be good to know.

C1+E (107) = vehicle GVW added to trailer MAM must not total more than 8250

Examples -
7500 + 750 = 8250
6500 + 1750 = 8250
5000 + 3250 = 8250
etc
