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.
