Answer 1

Answer:

Dear Uncle,

“I'm writing a letter to tell you about a nagging problem in my family that I haven't been able to solve on my own. I would greatly appreciate your help.

“The problem is X. (Explanation of X.)

“The reason I haven't solved it myself is Y. (Maybe explain Y.)

“I think you would be a big help solving the problem because of Z.

“Thanks in advance for any help or advice you can give me, and have a great day!

“love, niece/nephew”

The way you laid out your question is exactly how you should write the letter. Maybe with a bit more punctuation. :)
