If you meant
3(n)2(2n+2)=1/3 * (n+4)
then just multiply by 3 and expand stuff out:
9n6(2n+2)= (n+4)
9n12n12 = n + 4
4n = 16
n = 4
If you meant
3(n)2(2n+2)=1/(3(n+4))
then things get a bit more interesting and there is no real solution.

3n  4n 4 = 1/3(n+4)
n  4 = 1/3 (n+4)
multiply all parts by 3
3n 12 = n + 4
4n = 16
n = 4
