At present time I stay in Minsk, Belarus.
At hotel’s welcome desk I found a small booklet, advertising this country’s sites of interest (Brest, Vitebsk etc ) .
I have ended up with the following puzzle:

BOOKLET + BREST= BELARUS

It looks challenging, especially if solved without software.

ENJOY!

MATLAB software for this is quite concise):

s=perms('1234567890');
for i=1:length(s)
   belarus=s(i,1:7);
   brest=s(i,[1 5 2 7 8]);
   booklet=s(i,[1 9 9 10 3 2 8]);
   if str2num(booklet)+str2num(brest)==str2num(belarus)
      disp([booklet ' ' brest ' ' belarus])
   end
end
