The given set of equations are:

x + y = 3

x + y = -1

The graph these set of equations are:
graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+3+-+x%2C+-1+-+x%29

Here from the graph we observe that both the equations are parallel to each other and thus have no common solution.
Hence, the solution.
