The solutions to this system of equations are the points on the line y = 2x-4.

Explanation:

Note that the second equation is the first one multiplied by 3, therefore, the system can be reduced to only one of them.

We can rewrite the first one as y = 2x-4 and, as there are no more restrictions to the problem, any pair (x,y) that satisfies the equation is a solution to the system.

Hope it helps.
