Find the Values of the Variables for Which the Statement $$\left[ \begin{array} { c c } x + 3 & y + 4 \\7 & - 8\end{array} \right] = \left[ \begin{array} { c c } 8 & - 5 \\7 & k\end{array} \right]$$

Multiple Choice

Find the values of the variables for which the statement is true, if possible.
- $$\left[ \begin{array} { c c } x + 3 & y + 4 \\7 & - 8\end{array} \right] = \left[ \begin{array} { c c } 8 & - 5 \\7 & k\end{array} \right]$$

A) $x = 8 ; y = - 5 ; k = - 8$
B) $\mathrm { x } = 5 ; \mathrm { y } = - 9 ; \mathrm { k } = - 8$
C) $x = 5 ; y = - 8 ; k = 8$
D) $\mathrm { x } = - 5 ; \mathrm { y } = 9 ; \mathrm { k } = 8$
