Algebra Level 5

$\begin{cases} k_1 + k_2 + \cdots + k_n = 5n - 4 \\ \dfrac1{k_1} + \dfrac1{k_2} + \cdots + \dfrac1{k_n} = 1 \end{cases}$

Let $k_1, k_2, k_3, \ldots, k_n , n$ be all positive integers satisfying the system of equations above.

Find the sum of all distinct possible values of $n + k_1 + k_2 + \cdots + k_n$.
