Answer 4

(65 - y) + y + 8 + 26 + (42 - x) + x + z = 216 - 98
141 + z = 162
z = 162 - 141 = 21

Answer 10

For the previous problem, 234 is the value of the intersection of E and W. Not sure what they mean by cardinal number.

Sorry I don't have Skype.

The cardinal number may be just 1 as there is just one element, 234, in E intersection W.
