Question

Which equation is an identity?
A. -4y + 3 = -4y - 8
B. 15 - (6v + 6) = -6v - 9
C. 3w + 4 - w = 4w - 2(w - 2)
D. 5m - 4 = 6m + 5 - m

Answer 1

A is a false statement.
B is also false.
C comes out to 0 = 0 which is the identity property of 0

Answer 2

c.

Answer 3

3w + 4 - w = 4w - 2w + 4
2w + 4 = 2w + 4

Answer 4

Once both sides are equal, then it is an identity
