Choose the SLE that correctly describes the following problem.

The first shelf contains 4 boxes more than the second. Knowing that there are 24 boxes in total, find out how many boxes are there on the first and the second shelves ( $x_{1}$ and $x_{2}$ respectively).

Select one option from the list

\begin{cases}x_{1} - x_{2} = 4\\ x_{1} + x_{2} = 24\end{cases}

\begin{cases}x_{1} + x_{2} = 4\\ x_{1} = 24x_{2}\end{cases}

\begin{cases}4x_{1} = x_{2} \\ x_{1} = 24 - x_{2}\end{cases}

\begin{cases}x_{2} - x_{1} = 4\\ x_{1} + x_{2} = 24\end{cases}
