Quizplus · Accepted Answer

The system is inconsistent because the two equations represent parallel lines that never intersect, meaning there is no solution that satisfies both equations simultaneously.

Solve Using Cramer's Rule, If Possible {x+y=1x+y=−7\left\{ \begin{array} { l } x + y = 1 \\x + y = - 7\end{array} \right.{x+y=1x+y=−7​
