run o rin o pol = ?

From 'rin o al + ran o ul = ron o pal', we deduced R + U = 15.

From 'ran o el = 12', 'rin o al = 31', 'ron o pal = 46', and 'run o ren o ul = 75', we can infer values for individual words. For example, if we assume 'o' is a constant, we can solve for the other words. However, without more information or a clear pattern, it's impossible to determine the value of 'run o rin o pol'.
