The system is impossible.

#### Explanation:

To solve a system using elimination, you manipulate one of the equations until one of the variables have the same coefficient (in absolute value) in both equations.

Then, you add or subtract the two equations in order to cancel that variable.

For example, let's focus on the

When we multiply the second equation by

Now, if we subtract the two equations, we have

which shows that the system is impossible, since it leads to
