Solve the System $$\begin{array} { l } 2 x + 2 y + 5 z = - 19 \\2 x + 2 y + 3 z = - 13 \\6 x + 6 y + 11 z = - 44\end{array}$$

question 64

Multiple Choice

Solve the system. If a system has one unique solution, write the solution set. Otherwise, determine the number of solutions to the system, and determine whether the system is inconsistent, or the equations are dependent.
