Which classification describes the following syastem of equations? x=5 y=6 -x - y +z = 0
Papessa [141]

Answer:

Is a consistent independent system

Step-by-step explanation:

we know that

If a system has at least one solution, it is said to be consistent .  

If a consistent system has exactly one solution, it is independent .  

If a consistent system has an infinite number of solutions, it is dependent

If a system not have solution, it is said to be inconsistent

we have

x=5 ----> equation A

y=6 ----> equation B

-x-y+z=0 ----> equation C

substitute equation A and equation B in equation C

-5-6+z=0

Solve for z

z=11

The solution is the point (5,6,11)

The system has only one solution

therefore

Is a consistent independent system
