----------------------------------MISTAKES IN THIS WORK------------------------
Nick was x+8 when the time was 6 years ago, at which time sister was x-6.
Nick will always stay 14 years older than sister.
Six years ago, Nick was n-6 years old.
This is twice as much as his sister's current age.
Nick's past age = 2*(sister's current age)
n-6 = 2(n-14)
n-6 = 2n-28
n-2n = -28+6
-n = -22
n = 22
Nick is currently 22 years old
His sister is currently n-14 = 22-14 = 8 years old.
Six years ago, Nick was 22-6 = 16, which is double that of 8.
This is how we can confirm the answer is correct.
Answers:
Nick = 22 years old currently
Sister = 8 years old currently

Nick is NOT 34, and his sister is NOT 20, as that person states.
So, IGNORE the following: Sister is 20 now and Nick is 34 now. because it's RUBBISH!!
