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 NOW5 = 2(2) + 1 checks Wish You the Best in your Studies.

So, IGNORE the person who claims that it's NONSENSE, and that no solutions exist!
What he did and what he says are NONSENSE!
