Solve the following system of equations and identify a correct statement.
\[\begin{aligned}
\sqrt{x + y} & = \left |x\right | & &
\\x + y & = 4 & &
\end{aligned}\]
The system has two solutions \(\left [x_{1},y_{1}\right ]\),
\(\left [x_{2},y_{2}\right ]\), where
\(x_{1} = -x_{2}\).
The system does not have any solution.
The system has a unique solution.
