$- 2$ $-2$

Here's how I did it:

$\frac{c}{a - 4}$ $c/(a-4)$

You know that $a = 2$ $a=2$ and $c = 4$ $c=4$ , so you just plug them into the expression:

$\frac{4}{(2) - 4}$ $(4)/((2)-4)$

And simplify:
$\frac{4}{- 2}$ $4/-2$

$- 2$ $-2$

How do you evaluate ca−4c/(a-4) given a= 2, b= 7, and c= 4?
