Answer 3

To evaluate the expression $x - 7(x + 13)$ when $x = 9$, simply substitute $x$ with 9 and perform the calculations:

$9 - 7(9 + 13)$

First, evaluate the expression inside the parentheses:

$9 - 7 \times 22$

Now, perform the multiplication:

$9 - 154$

Finally, perform the subtraction:

$-145$

So, $x - 7(x + 13)$ when $x = 9$ is $-145$.
