A gathering of 30 people, x speaks hausa and 15 speak yoruba. If 5 people speak both languages, find how many people that speak
1. Hausa
2.yoruba only
3.hausa only
To find the number of people who speak Hausa only, we need to subtract the 5 people who speak both languages from the total number of Hausa speakers.
1. Hausa: x - 5
To find the number of people who speak Yoruba only, we need to subtract the 5 people who speak both languages from the total number of Yoruba speakers.
2. Yoruba only: 15 - 5 = 10
To find the number of people who speak Hausa only, we subtract the number of people who speak Yoruba only and the number of people who speak both languages from the total number of people.
3. Hausa only: 30 - (x - 5) - (15 - 5) = 30 - x + 5 - 10 = 25 - x
