1. **State the problem:** We are given a system of equations:
$$x + y = 5$$
$$x^2 + y = 11$$
One point of intersection is $(3, 2)$. We need to find the coordinates of the other point where the line and parabola intersect.
2. **Use substitution:** From the first equation, solve for $y$:
$$y = 5 - x$$
3. **Substitute into the second equation:** Replace $y$ in the second equation with $5 - x$:
$$x^2 + (5 - x) = 11$$
4. **Simplify the equation:**
$$x^2 + 5 - x = 11$$
$$x^2 - x + 5 = 11$$
$$x^2 - x + 5 - 11 = 0$$
$$x^2 - x - 6 = 0$$
5. **Factor the quadratic:**
$$x^2 - x - 6 = (x - 3)(x + 2) = 0$$
6. **Solve for $x$:**
$$x - 3 = 0 \Rightarrow x = 3$$
$$x + 2 = 0 \Rightarrow x = -2$$
7. **Find corresponding $y$ values:**
For $x = 3$:
$$y = 5 - 3 = 2$$
For $x = -2$:
$$y = 5 - (-2) = 5 + 2 = 7$$
8. **Answer:** The other point of intersection is $(-2, 7)$.
