Answer:
- add x to both sides
- divide both sides by 4
- add 20 to both sides
- divide both sides by 3
Step-by-step explanation:
Your steps in order would be ...
- add x to both sides
- divide both sides by 4
- add 20 to both sides
- divide both sides by 3
__
Executing these steps, we get ...
4(3x -20) = 16 . . . . . add x
3x -20 = 4 . . . . . . . . divide by 4
3x = 24 . . . . . . . . . . .add 20
x = 8 . . . . . . . . . . . . . divide by 3, giving the solution

<em>Additional comment</em>
If you were to distribute the 4 first, you would have ...
12x -80 -x = 16 -x
Now, you can add x and add 80 to get ...
12x -80 = 16
12x = 96
Then dividing by 12 gives ...
x = 8
You will notice that these steps do not match steps available in your list.
