Hi guys I have the following equation:

$$x = \dfrac{a + b \times c - b}{c}$$

This is what I know about each variable:
$$a \ge 64$$
$$b \ge 0$$
$$8 \le c \le a$$

My questions is there a concise way for me to pick a, b, and c so that x will always be a positive integer >= 8. 

For example if $a = 64$; $b= 0$; $c = 8$ (the smallest possible values for each)

$x = (64 + 0 \times 8 - 0)/8$

$x = 8$ which is a positive integer $\ge 8$

However, if let's say $a = 200$; $b = 2$; $c = 10$

$x = (200 + 2 \times 10 - 2)/10$

$x = \dfrac{218}{10}$ which is $21.8$ and is not a positive integer greater than or equal to $ 8$

How can I always know that $x$ will be a positive integer?? Thanks!
