The equations have **no** solutions!

#### Explanation:

If

adding them would yield the contradiction

So, no such

Alternatively, the two equations represent two straight lines that have the same slope (namely, -2 ) and different intercepts (4 and -4, respectively). So, they are parallel lines that never intersect.
