5w +8-w = 6w -2(w-4)

4w +8 = 6w -2w +8

4w +8 =4w +8

This is an identity


7m-2 = 7m+4


8y+9 = 8y-3


11-2v-3 = -2v-8

8-2v = -2v-8

Answer:

5w + 8 - w = 6w - 2(w - 4) is an identity

Step-by-step explanation:

Lets simplify equation equation and check

5w + 8 - w = 6w - 2(w - 4)

4w + 8= 6w- 2w+ 8

Combine like terms

4w + 8=4w+8 Both sides are equal

7m - 2 = 8m + 4 - m

7m - 2 = 7m + 4 both sides are not equal

8y + 9 = 8y -3 Both sides are not equal

11 - (2v + 3) = -2v - 8

11 -2v - 3 = -2v - 8

-2v +8= -2v - 8 both sides are not equal
