Solve the system using the addition method. If the system is inconsistent and has no solution, state this. If the system is dependent, write the form of the solution for any real number $x$.
-$x+y=9$
$\mathrm{x}+\mathrm{y}=-1$
A) $(9,-1)$
B) $(0,8)$
C) $(x, 8-x)$
D) $\varnothing$

Question

The system is inconsistent because adding the equations together cancels out both variables, leading to an impossible statement (e.g., $9 = -1$), indicating no solution exists.
