Verify that the values of the variables listed are solutions of the system of equations.
-$$\left\{ \begin{array} { l } 
x + y = - 1 \
x - y = 11 \
\end{array} \right.$$

x = 5 , y = - 6

A) solution
B) not a solution

Quizplus · Accepted Answer

Substituting $x = 5$ and $y = -6$ into both equations: For the first equation, $5 + (-6) = -1$, which is true. For the second equation, $5 - (-6) = 11$, which is also true. Therefore, $x = 5$ and $y = -6$ satisfy both equations, making them a solution to the system.
