Can you get this started based on the help you got a little while ago?
Let m = man
Let s = son
Currently: give me the equation
four years from now: give me the equation.

You are correct with the m = 4s
for years from now the man will be m+4
and the son will be s +4
Now, what is their age relationship.
The man will be 3 times older than his son.
m + 4 = 3(s+4)
use that equation and m = 4s
to find their ages.
You have to read carefully and look for key words. For example, 3 times means to multiply by 3.
Four years from now means you have to add 4 years to their age.
If it said 4 years ago then you would subtract.
