I answered this problem for someone else earlier today.
You can probably find it in the list of links below.

1. Find the number of students who take only one language:
- Number of Spanish students = 38
- Number of French students = 38
- Number of German students = 46
- Total number of students who take only one language = Number of Spanish students + Number of French students + Number of German students
2. Find the number of students who take two languages:
- Total number of foreign language students = 103
- Number of students who take at least 2 languages at once = 19
- Number of students who take two languages = Total number of students who take at least 2 languages at once - Number of students who take all three languages
3. Calculate the number of students who take all three languages:
- Number of students who take all three languages = Total number of foreign language students - Number of students who take only one language - Number of students who take two languages
By following these steps, you can determine the number of students who take all three languages at once.
