The graph of a system of a quadratic function, $y = x^{2} - 2 x - 3$ , and a linear function, $y = x + 1$ , is shown. What is the sum of the $x$ -coordinates of all solutions to this system?

(A graph showing the parabola $y = x^{2} - 2 x - 3$ and the line $y = x + 1$ intersecting at $(- 1, 0)$ and $(4, 5)$ would be provided.)
