The image you uploaded contains several mathematical word problems, but it's upside down. Let me rotate and summarize them, starting from what I can read:

1. First problem (b):

   • A system of linear equations is given: $3x - 4y = z - 3$ $4x + 2y = 3z - 8$ $2x - y = z - 5$
   • The instruction seems to ask for solving this system.

2. Second problem (a):

   • Another system of equations is given, but the content isn't fully visible. I can help better if I extract the equations individually or if you rotate the image for clarity.

Would you like me to start solving the system of equations in the first problem (b) or attempt to extract more details from the rest of the image? Let me know!

Also, here are 5 related questions to deepen your understanding:

1. What techniques can be used to solve systems of linear equations?
2. How can you check the consistency of a system of equations?
3. What are some applications of solving systems of linear equations?
4. How does substitution differ from elimination in solving systems?
5. What happens when a system of linear equations has no solution?

Tip: Always write systems of equations in a structured way to avoid confusion and make solving easier.
