Question 262241: In a certain club, 14 members speak Spanish, 9 members speak French and 18 members speak either French or Spanish. How many speak both languages? Answer by solver91311(24713) (Show Source):
If you add the number of Spanish speakers (14) to the number of French speakers (9), you get a total of 23. But there are only 18 total who speak either Spanish or French, so the number of people who speak both must be the difference, 23 - 18 equals 5.
