So if you were to draw this out on a piece of paper going one person at a time or just doing it in your head. You have a table where the seating goes as followed
Adam, Ethan, Claudia
--------------------------------
Braden, Felix, Diego
This seating chart works for everything about this question and as per usual if I'm wrong flame me
Distribute -pd-pz=-2z+59 add 2z both sides -pd-pz+2z=59 add pd to both sides -pz+2z=59+pd 2z-pz=59+pd undistribute z z(2-p)=59-pd divide bot sides by 2-p
