Hi!
To find the value of n in the given equation, multiply both sides by 3.
That way, you'll clear the fractions and solving for n will be easier.

Watch what happens:

On the LHS, the 3's cancel out, and we're left with 2n:

Now, divide both sides by 2:

Voila! There's our solution.
Have a nice day!
I hope this helps.
