Answer 2

Ok so, it isn't correct because you can't subtract 8x from 56. Basically to get rid of the 8, you divide 56 by 8.

Answer 3

Step 1 is correct. But the other 2 steps should look something like this:
8x=56
--- ---
8 8

Answer 4

For part 2, we know that 56 can be divided by 8, but is there anything else that could go into the equation to make it true?
