Determine the value of each variable.
-$\left[ \begin{array} { r r r } - 5 & 1 & x \ 7 & y & - 4 \end{array} \right] = \left[ \begin{array} { r r r } m & 1 & 2 \ n & 4 & p \end{array} \right]$
A) $m = - 5 , x = 2 , n = 1 , y = 4 , p = - 4$
B) $\mathrm { m } = 7 , \mathrm { x } = 1 , \mathrm { n } = - 5 , \mathrm { y } = 4 , \mathrm { p } = - 4$
C) $m = - 5 , x = 2 , n = 7 , y = 4 , p = - 4$
D) $m = - 5 , x = 1 , n = 7 , y = 4 , p = - 4$
