Michael is 3 more than twice John’s age. In 3 years Michael will be 3 years older than John. What is age of both boys

I interpret your condition as
Michael is 3 more than twice John’s age. In 3 years Michael will be 3 years older than John. What is age of both boys
Solution
If in 3 years M will be 3 years older than J, it means (at least, in frame of this problem) that M is ALWAYS 3 years older than J:
M = J + 3
So, what you have from the condition now, is THIS:
M = 2J + 3, or
J+3 = 2J + 3 ====> J = 2J ====> J = 0.
Since the answer J = 0 in age problems is equivalent to NONSENSE, the problem DOES NOT MAKE SENSE.
-----------
The different interpretation of the condition is also possible:
Michael age is 5 times John’s age. In 3 years Michael will be 3 years older than John. What is age of both boys.
reading "3 more than twice" as "5 times".
But such interpretation is mocking a reader, therefore, I don't want to continue from this point . . .
