---the system of simoultanious equation
X+2y+z=6
2x+y+2z=6
X+y+z=5​

The system of equations has no solution.

Step-by-step explanation:

Let the following system of linear equations:

(1)

(2)

(3)

Since the quantity of equations and variables are the same, there is only one solution to this system. First, we clear in (3):

And make substitution both in (1) and (2):

(4)

(5)

Which lead to a contradiction, since . Therefore, the system of linear equations has no solution.
