Your ultimate goal is to get the variable secluded all by itself. You'll have to use the opposite operation to do this and remember, what you do to one side, you have to do to the other.
1. 9s + 3 = 57
2. Subtract 3 from each side. This will result in 9s = 54
3. To undo the multiplication of 9s you'll divide both sides by 9. 9s/9 = 54/9
4. The ending result is: s=6
5. Go back and check your work by substituting it in your original equation.
It means that it does not equal to that certain amount, which is why they put a line across it

I have my correct answers in the photo so just read from that :) <3
Answer:
The associative property will be:

So, Option C is the correct option.
Step-by-step explanation:
We need to write the expression that uses the associative property to make it easier to evaluate: 
The associative property of multiplication states that: 
So, For the given expression:

The associative property will be:

So, Option C is the correct option.
