Let $a$, $b$, $c$, $x$, $y$, and $z$ be real numbers that satisfy the three equations:
\begin{align*}
  15x + by + cz &= 0 \\
  ax + 25y + cz &= 0 \\
  ax + by + 45z &= 0.
\end{align*}
Suppose that $a \neq 15$, $b \neq 25$ and $x \neq 0$. What is the value of
\[ \frac{a}{a - 15} + \frac{b}{b - 25} + \frac{c}{c - 45} \, ?\]
