It would be D , please tell me if I’m correct
The answer would come out to 132 :) I just divided the numbers one way you could do it is divide the numbers separate Hope this helps! :)
Answer:
either of Step 3 or Step 4
Step-by-step explanation:
At Step 3, -1 is added to both sides of the equation. Technically, this is correct (not an error), but it does not lead to a solution to the equation (so, could be considered to be an error). Adding +1 to both sides of the equation would lead more directly to a solution.
__
At Step 4, x -1 -1 is simplified to x. This is an error, as the correct simplification is x-2, so the equation after this step should read x-2 = 5. If Step 3 had been executed by adding +1 to both sides of the equation, then the simplification here would be x=7.

Answering "why" someone does something is always tricky. One can project one's own interpretation onto the actions of others, but one never really knows whether that is accurate or not.
The "why" in this case could go back to the motivation of the problem's author, which may be to see if the student can recognize that the opposite of -1 is +1, or that the sum -1-1 is not zero.
___
My guess is that Step 3 is considered to be the erroneous step, and that choosing Step 4 will get you into a losing argument with your grader.
Answer:
- The numerator has 2 terms
- 4 is a term in the numerator
- x + 2 is a factor of the numerator
Step-by-step explanation:
The expression as written has a numerator with the terms 2x and 4. That is, there are two terms, and one of them is 4.
The expression can be factored as ...
So, you can see that x+2 is a factor of the numerator.
___
4 is a <em>term</em> in both numerator and denominator, but is not a <em>factor</em> of either one. (x +2) is a factor of both, but that fact is not on your list.
