**Evaluate \[2-(-4)+(-y)\] where \[y = 7\].**

To evaluate the expression \(2 - (-4) + (-y)\) where \(y = 7\), follow these steps:

1. **Substitute \(y = 7\) into the expression:**
   \[
   2 - (-4) + (-(7))
   \]

2. **Simplify each part of the expression:**
   - \(2 - (-4)\) is the same as \(2 + 4\) (since subtracting a negative number is the same as adding the positive number).
   \[
   2 + 4 = 6
   \]
   - Next, we have \(-(7)\), which simplifies to \(-7\).

3. **Combine the results:**
   \[
   6 + (-7) = 6 - 7 = -1
   \]

So, the evaluated expression is \(-1\).
