$y = \frac{x - 5}{x^{2} - 6x + 5}$
$y = \frac{x - 5}{(x - 1)(x - 5)}$
$y = \frac{1}{x - 1}$

Put x = 3, y = 2 and z = 5 to the given expression $10x^3y^{-5}z^{-2}$ :

$10(3^3)(2^{-5})(5^{-2})\qquad\text{use}\ a^{-n}=\dfrac{1}{a^n}\\\\=\dfrac{10(27)}{(2^5)(5^2)}=\dfrac{270}{(32)(25)}=\dfrac{270}{800}=\dfrac{27}{80}$
