Write a System of Equations to Describe the Situation $\left\{ \begin{array} { l } x - y = 5 \\2 x - 3 y = - 9\end{array} \right.$

Write a system of equations to describe the situation. Do not solve the system.
-One number is 5 more than another number. If you add 9 to 2 times the first number, the result is 3 times the second number.

A) $\left\{ \begin{array} { l } x - y = 5 \\2 x - 3 y = - 9\end{array} \right.$
B) $\left\{ \begin{array} { l } x - y = 5 \\2 x - 3 y = 9\end{array} \right.$
C) $\left\{ \begin{array} { l } x - y = 5 \\- 2 x + 3 y = - 9\end{array} \right.$
D) $\left\{ \begin{array} { l } x + y = 5 \\2 x - 3 y = - 9\end{array} \right.$
