Which sum or difference is equivalent to the following expression?

3-2x over 3

1. 9 - 6x
2. 1 - 2/3
3. 1 + 2 x/3
4. 1 - 2 x/3

(3-2x)/3 = 3/3 - 2x/3

so, what do you think?

1 - 2 x/3 right?

looks good to me

It was correct, thank you for your help.

To find the sum or difference that is equivalent to the expression (3 - 2x) / 3, we need to simplify the expression.

First, let's distribute the division by 3 to both terms inside the parentheses:
3/3 - (2/3)x

Simplifying further:
1 - (2/3)x

Now, we can see that the equivalent expression is 1 - (2/3)x. Therefore, the correct option is number 4, 1 - 2x/3.
