Answer
No Solution
Work Step by Step
For the first equation $3x-y=4$, the $x$ and $y$ intercepts are found as $(\frac43,0)$ and $(0,-4)$ by substituting $0$ for $y$ and $x$ values in the equation respectively.
Similarly, for the second equation $6x-2y=4$, the $x$ and $y$ intercepts are found as $(\frac23,0)$ and $(0,-2)$ by substituting $0$ for $y$ and $x$ values in the equation respectively.
Now, graph each equation as a line passing through the intercepts. It can be observed from the graph that both lines form two parallel lines which do not intersect. So, no solution exists as they do not intersect.
The graph is as below.
