A man is currently 4 times as old as his son. In 4 yrs from now hell be 3 times as old as his son will be then. How old is his son now??

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. 
Okay : Currently man is : 4s
Son : s
4 yrs froom now:
Man
3(s3)
Son: s3 
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. 
Thanks alot :) that helpe me alot

father=32
son=8
