Ответ:
For this case we have the following system of equations:
To solve, we substitute the second equation in the first:
As noted, equality is not fulfilled. Thus, the system has no solution.
It can also be observed that the equations are:
That is, they have the same slope,
, so the lines are parallel. If the lines are parallel, they never intersect.
The system has no solution
