Write a System of Equations in X and Y Describing $\left\{ \begin{array} { l } x - y = 5 \\ 3 x - 4 y = - 8 \end{array} \right.$

Multiple Choice

Write a system of equations in x and y describing the situation. Do not solve the system.
-One number is 5 more than another number. If you add 8 to 3 times the first number, the result is 4 times the second number.

A) $\left\{ \begin{array} { l } x - y = 5 \\ 3 x - 4 y = - 8 \end{array} \right.$
B) $\left\{ \begin{array} { l } x - y = 5 \\ - 3 x + 4 y = - 8 \end{array} \right.$
C) $\left\{ \begin{array} { l } x - y = 5 \\ 3 x - 4 y = 8 \end{array} \right.$
D) $\left\{ \begin{array} { l } x + y = 5 \\ 3 x - 4 y = - 8 \end{array} \right.$
