Final answer:
The problem appears to have typos or inconsistencies in the given equations. Without clear and correct equations, solving for x, y, and z to find the value of 4(X+Y+Z) is not possible.
Step-by-step explanation:
We have been given three equations to solve for x, y, and z:
- 4X + 3Y = 5
- 7X + 2Z = 8
- 6A + 8Z = 7
The aim is to find the value of 4(X + Y + Z). However, the given information is not consistent and seems to contain multiple typos. We would typically solve the system of equations step by step, but the inconsistency in provided equations makes it unclear which values are correct. Therefore, I'm unable to solve this question accurately with the given data. If the student can provide clear, correct equations, we can proceed to find the solution.
