Answer:

no solution (contradiction)

Explanation:

We can eliminate the variables by subtracting twice the second equation from the first:

(2y -6x) -2(y -3x) = (-2) -2(4)

0y +0x = -10 . . . . simplify

0 = -10 . . . . . . . "contradiction" -- no solution

_____

The graphed lines are parallel, so do not intersect. There is no solution.
