x = both
dog owners....22 - x
cat owners ...27 - x
neither = 11

x + (22 - x) + (27 - x) + 11 = 50
49 + 11 - x = 50
60 - x = 50
-x = -60 + 50
-x = -10
x = 10...so 10 owned both

owned cats ...27 - 10 = 17
owned dogs...22 - 10 = 12

what if it says find the number of each region, that's what was addressed @queenie

queenie · Answer

we found numbers in each region...
the dog region = 12
the cat region = 17
the region that included both cats and dogs = 10
and then there is the one that is neither = 11
for a total of 50
