Simplify: `(1/3y^2-4/7y+11)-(1/7y-3+2y^2)-(2/7y-2/3y^2+2)`

Explanation

To simplify the expression \((1/3y^2 - 4/7y + 11) - (1/7y - 3 + 2y^2) - (2/7y - 2/3y^2 + 2)\), we will follow these steps:

### Step 1: Remove the parentheses
We start by distributing the negative signs across the terms in the parentheses:

\[ 1/3y^2 - 4/7y + 11 - 1/7y + 3 - 2y^2 - 2/7y + 2/3y^2 - 2 \]
