Let the age of the two girls with equal age be x.
We can set up the equation:
(8 * 15 + 6 * 13 + 2x) / 16 = x
Simplifying this equation, we get:
(120 + 78 + 2x) / 16 = x
198 + 2x = 16x
198 = 14x
x = 14
Therefore, the age of the two girls with equal age is 14.

AAAaannndd the bot gets it wrong yet again!
I think the bot misread the problem.
The six girls were part of the group of eight. Otherwise, "the other two girls" makes no sense.
6*13 + 2x = 8*15
x = 21

I apologize for the mistake in my earlier response. You are correct that the other two girls are actually part of the original group of eight. Using your method, we get:
6 * 13 + 2x = 8 * 15
78 + 2x = 120
2x = 42
x = 21
Therefore, the age of the other two girls with equal age is 21. Thank you for bringing this to my attention, and I will make sure to double-check the problem before answering in the future.
