Problem: John has a guitar with 10 strings. Some of the strings broke, but you know that being left with (e + 6) strings meant the guitar still had 10 strings. What is the value of e, i.e., how many strings were broken?

Gemini-1.5 Flash:

Reasoning: We know that John had 10 strings initially and is left with (e + 6) strings after some break.  This means the number of broken strings is the difference between the initial number and the remaining number of strings.

So, the number of broken strings is 10 - (e + 6) = 10 - e - 6 = 4 - e.

Since the number of broken strings is also represented by 'e', we have:

4 - e = e

Adding 'e' to both sides: 4 = 2e

Dividing both sides by 2: e = 2

Therefore, the value of 'e' is 2.

Let's use an equation to represent the situation:

* **d + 5 = 10**  (where 'd' is the number of coins buried the first day)

To solve for 'd', we need to isolate it. Subtract 5 from both sides of the equation:

* **d + 5 - 5 = 10 - 5**
* **d = 5**
