Answer 3

[AI-generated answer — Explain Bot]

In this question, Angie is solving the equation -x + 7 = -11.

Let's go through Angie's solution step by step:

1. Angie starts by adding 7 to both sides of the equation.
-x + 7 + 7 = -11 + 7
This simplifies to:
-x = -4

2. Next, Angie subtracts 7 from both sides.
-x - 7 = -4 - 7
This simplifies to:
-x = -11

At this point, Angie made an error. She subtracted -11 and -7 incorrectly. The correct subtraction would be -11 - 7 = -18, not -11 - (-7) = -4.

Therefore, the correct response is: "She subtracted -11 - 7 and -7 incorrectly."
