Answer 2

To evaluate the expression $7x - (x + 5)$ when $x = -8$, substitute $-8$ for $x$ in the expression and simplify:

$7 \cdot (-8) - ((-8) + 5)$

First, calculate the products and sums inside the parentheses:

$= -56 - (-3)$

Next, simplify the subtraction:

$= -56 + 3$

Finally, add the numbers:

$= -53$

Therefore, when $x = -8$, $7x - (x + 5) = -53$.
