Answer:

no solution

Explanation:

Divide both sides of the second equation by 2.

2x - 4y - z = 8

The first equation is

2x - 4y - z = 10

Subtract the simplified second equation from the first equation.

2x - 4y - z = 10

- 2x - 4y - z = 8

---------------------------

0 = 2

Since 0 = 2 is false, there is no solution.
