To determine which system of equations has no real solutions, we can analyze each pair of equations:

1. **y = -x² + 2 and y = x²**
- The first equation is a downward-opening parabola with its vertex at (0, 2).
- The second equation is an upward-opening parabola with its vertex at (0, 0).
- These two parabolas do intersect at two real points, so this system has real solutions.

2. **y = x² + 1 and y = -x² - 1**
- The first equation is an upward-opening parabola with its vertex at (0, 1).
- The second equation is a downward-opening parabola with its vertex at (0, -1).
- The distance between the vertices and the nature of their openings (one opens up and the other opens down) shows that they are always apart; thus, this system has no real solutions.

3. **y = x² and y = x + 1**
- The first equation is an upward-opening parabola and the second is a linear equation.
- They will intersect at two real points.

4. **y = 3x + 1 and y = 2x + 2**
- These are both linear equations. By rearranging, we can find their point of intersection:
* 3x + 1 = 2x + 2 -> x = 1.
* When x = 1, y = 4.
- So this system has a real solution.

From the analysis above, the only pair of equations that has no real solutions is:

**y = x² + 1 and y = -x² - 1.**
