With these problems it's always good to write down what you know using variables. Let the father's age now be $\displaystyle x$ and the son's age now be $\displaystyle y$.
Now we can write a number of equations based on what we're told:
In 5 years time father will be 3 times as old as his son: $\displaystyle x+5 = 3(y+5)$
four years ago father was 6 times as old as his son: $\displaystyle x-4 = 6(y-4)$
You now have a pair of simultaneous equations in x and y so you can solve it. In this case it would be easier to use elimination by taking the second equation from the first
