It looks like you have uploaded a system of linear equations. Let me rewrite them for clarity:

1. $3x + 5y - 4z = 0$
2. $2x - 3y + z = 5000$
3. $-x + 4y + 6z = 13000$

Would you like me to solve this system of equations for you? Let me know if you'd like additional details or have any specific questions!
