Which expression represents the difference of (3y+2)-(y-1)?

I put 2y+ 3 for my answer.

Correct.

Thanks a lot

You're welcome.

To find the difference between the expressions (3y+2) and (y-1), you need to subtract one expression from the other. Let's break it down step by step:

Step 1: Distribute the negative sign to the second expression.
- (y - 1) becomes -y + 1.

Step 2: Now, we can combine like terms.
(3y + 2) - (y - 1) becomes 3y + 2 - y + 1.

Step 3: Simplify further by combining like terms.
Combine the terms with 'y': 3y - y = 2y.
Combine the constant terms: 2 + 1 = 3.

So, the final expression representing the difference is 2y + 3.

Therefore, your answer of 2y + 3 is correct. Well done!
