system%28c-8=%282d-8%29%2B1%2Cc%2B8=%287%2F6%29%2A%28d%2B8%29%29------exact translation of the description; c for Charles' age and d for David's age

system%28c-8=2d-7%2C6c%2B48=7%28d%2B8%29%29

12d%2B56=7d%2B56
The problem description is nonsense.
NO SOLUTION.

Hi
Let c and d represent their respective ages NOW:
 c- 8 = 2(d-8) + 1
 c + 8 = (7/6)(d+8)

c  -   2d = -7
c - (7/6)d = 56/6 - 48/6

- c  +   2d = 42/6
  c - (7/6)d = 8/6
       (5/6)d = 50/6
            d = 10, David's age NOW

c = 13 NOW +c+=+%287%2F6%29%2810%2B8%29+-+8
  5 = 2(2) + 1   checks   c-+8+=+2%28d-8%29+%2B+1
Wish You the Best in your Studies.

There's nothing "FUNNY" about this problem. 
The lady tutor is correct. INDEED, highlight_green%28matrix%281%2C4%2C+David%2C+is%2C+10%2C+years-old%29%29
So, IGNORE the person who claims that it's NONSENSE, and that no solutions exist!
What he did and what he says are NONSENSE!
