# Recurring Styles 10 - Simultaneous System of Recurrences!

$\large{\begin{cases} D_{n+1} = 8L_n + 39n - 9 \\ D_n + 9n = L_n + 6n = K_{3n} + 33n \\ L_0 = D_0 = K_0 = 1 \end{cases}}$

Solve the system of recurrences with respect to $$K_n, L_n$$ and $$D_n$$ in terms of $$n$$ for $$n \geq 0$$. Submit the value of $$(D_6 - K_{15} - L_5)$$ as your answer.
