I would say identity because:
6.8- 4.2b=5.6b-3
6.8=9.8b-3
9.8=9.8b

Answer:

1 = b

Step-by-step explanation:

6.8 - 4.2b = 5.6b - 3

First you must add 4.2b to both sides.

Then you will get 6.8 = 9.8b - 3.

Next you must add 3 to both sides.

You will then get 9.8 = 9.8b

Finally divide both sides by 9.8.

You will be left with  1 = b
