For this case we have the following expressions:
Rewriting the second equation we have:
It is observed that by multiplying the first equation by 2, the second equation is obtained.
Thus, the equations are linearly dependent and since the lines are equal then they are intercepted in infinite points. Therefore, the system has endless solutions.
