To model the equation \(5x + (–6) = 6x + 4\) using algebra tiles, we need to represent both sides of the equation using tiles that represent the variables (x-tiles) and the constants (unit tiles).

Let's break down the equation:

- On the left side, we have \(5x\) and \(-6\).
- This can be represented with **5 positive x-tiles** (for \(5x\)) and **6 negative unit tiles** (for \(-6\)).

- On the right side, we have \(6x\) and \(4\).
- This can be represented with **6 positive x-tiles** (for \(6x\)) and **4 positive unit tiles** (for \(4\)).

Now, let's check what is needed to model the equation:

1. **5 negative x-tiles on the left** - **Not needed** (We need positive x-tiles, not negative).
2. **6 positive x-tiles on the right** - **Needed** (This represents \(6x\)).
3. **4 positive unit tiles on the right** - **Needed** (This represents the constant \(4\)).
4. **6 negative x-tiles on the right** - **Not needed** (We need positive x-tiles, not negative).
5. **6 negative unit tiles on the left** - **Needed** (This represents \(-6\), since we require negative unit tiles to model \(-6\)).

In summary, the correct selections for modeling the equation are:

- **6 positive x-tiles on the right**
- **4 positive unit tiles on the right**
- **6 negative unit tiles on the left**
