N3 is solved below.



<pre>
From the condition, we have two equations

    V + R = 57     (1)    ("the sum of their ages is 57")

    V = 4*R + 2    (2)    ("When Vince’s age is divided by Raven’s age")


From equation (1), express R = 57 - V and substitute it into equation (1).  You will get

    V = 4*(57-V) + 2.


Simplify and find V

    V = 4*57 - 4V + 2

    V + 4V = 4*57 + 2

      5V   =   230

       V   =   230/5 = 46.


<U>ANSWER</U>.  Vince is 46 years old.  Raven is  57-46 = 11 years old.

Solved.
