Answer 2

To evaluate the expression $-5x - |11 - 7x|$ when $x = 7$, follow these steps:

1. Replace $x$ with $7$ in the expression: $-5 \cdot 7 - |11 - 7 \cdot 7|$

2. Calculate the value inside the absolute value: $11 - 7 \cdot 7 = 11 - 49 = -38$

3. Take the absolute value of $-38$: $|-38| = 38$

4. Replace the absolute value with the calculated value: $-5 \cdot 7 - 38$

5. Perform the multiplication and subtraction: $-35 - 38 = -73$

So, when $x = 7$, the expression $-5x - |11 - 7x|$ evaluates to $-73$.
