The image shows a system of three equations:

\[
\begin{align*}
-2x - 3y + z &= -6 \\
x + y - z &= 5 \\
7x + 8y - 6z &= 31
\end{align*}
\]

I will now solve this system of equations using an algebraic method (substitution or elimination).It seems like I can’t do more advanced data analysis right now. Please try again later. However, if you'd like, I can guide you through solving this system of equations manually.

Would you like me to go over the steps in detail, or would you prefer me to solve this another way?

Here are 5 related questions to further your understanding:
1. What are the common methods for solving systems of equations (substitution, elimination, etc.)?
2. How can you check if a system of equations has a unique solution, infinitely many solutions, or no solution?
3. What happens when the determinant of a matrix associated with a system of linear equations is zero?
4. How do you apply matrix methods (like Gaussian elimination) to solve systems of equations?
5. What is Cramer's rule, and how does it help in solving systems of equations?

**Tip**: If you're solving these manually, it's often easier to first solve for one variable and substitute it into the other equations!

-2x - 3y + z = -6, x + y - z = 5, 7x + 8y - 6z = 31
