Let's break down the problem from the image step by step.

We are given:

$x - 2 = -7$

First, solve for $x$:

$x = -7 + 2 = -5$

Now that we know $x = -5$, we need to evaluate the expression:

$\frac{8 - 4x}{4}$

Substitute $x = -5$ into this expression:

$\frac{8 - 4(-5)}{4} = \frac{8 + 20}{4} = \frac{28}{4} = 7$

Thus, the value of the expression is 7.
