I have a question from my C++ textbook that asks:

update the value of an int variable x by adding 5 to it. 

my x variable is initialized at 25 right now. 

How would I do this? (I apologize if this seems confusing...feel free to correct me if I said a word that was incorrect) 

I used yahoo and they said the answer is

```
int x=1; 
x=x+1; 

```

This makes no sense though... it clearly says to add 5. 
Let me know if I'm misunderstanding something
