3. Which equation is an identity?

A. –3y + 3 = –3y – 6

B. 9 – (2v + 3) = –2v – 6

C. 3w + 8 – w = 4w – 2(w – 4)

D. 7m – 5 = 8m + 7 – m

i think B but I’m not 100% sure lol

Step-by-step explanation:

Here’s what I found on this app

3w + 8 - w = 4w - 2(w - 4)

2w + 8 = 4w - 2w + 8

2w + 8 = 2w + 8

0 = 0

The answer is B. 

If you look for where the two graphs intersect, you'll see that the x values of the ordered pairs are -4 (for the intersection in quadrant 2) and roughly 2.5 (for the intersection in quadrant 4). This problem is just asking you to look for those values.
