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.
