Answer 1

Which equation is an identity?
A. 11 – (2v + 3) = –2v – 8
B. 5w + 8 – w = 6w – 2(w – 4)
C. 7m – 2 = 8m + 4 – m
D. 8y + 9 = 8y – 3

Answer 2

C. 7m – 2 = 8m + 4 – m

Answer 3

I apologize for the incorrect previous response. The correct answer is:

D. 8y + 9 = 8y - 3

This equation is an identity because by simplifying both sides of the equation, we get:

8y + 9 = 8y - 3

8y - 8y + 9 = 8y - 8y - 3

9 = -3

The equation simplifies to 9 = -3, which is not true. Therefore, none of the given options are identities.
