Answer:

System is inconsistent and equations are mutually dependent.

Step-by-step explanation:

Let divide each linear equation by its smallest coefficient:

$x-4\cdot y = 2$

By using the elimination method on variable x, the following equivalence appears:

$2-4\cdot y = 2-4\cdot y$

Since one of the equation is a multiple of the other one, there is not an unique solution and equations are mutually depedent. The system is inconsistent.
