Mathematical age problem
Solution. Suppose my nephew is X years old and Uncle Zeyan is 44-x years old.

Uncle Yan is different from my nephew. (44-x)-x=44-2x years old.

One year when Uncle Yan was X years old, my nephew x-(44-2x)=3x-44.

Judging from the meaning of the question.

x=(3x-44)*4

1 1x=44*4

x= 16。

44- 16=28

Answer: Uncle Yan is 28 years old and nephew 16 years old.
