Question 122

Short Answer

Use Cramer s rule to find the solution set for the system. (x−y−5z=−85x+6y−7z=−15−x+5y−z=−8)\left(\begin{array}{l}x&-&y&-&5 z&=&-8 \\5 x&+&6 y&-&7 z&=&-15 \\-x&+&5 y&-&z&=&-8\end{array}\right) If the equations of the system are dependent, or if a system is inconsistent, so indicate. In those cases enter dependent or inconsistent .
