x + y = -1
Thank you so much,

Hi Sher,
I didn't see this one earlier.
Solve the system by graphing:

E1: x + y = 3
E2: x + y = -1
These are parallel lines that never intercect. This has no solution.
For E1:
Let x=0 and y=?
0+y=3
y=3 Plot (0,3)
Let y=0 and x=?
x+0=3
x=3 Plot (3,0)
Connect the points and you have this line:

For E2:
Let x=0 and y=?
0+y=-1
y=-1 Plot (0,-1)
Let y=0 and x=?
x+0=-1
x=-1 Plot (-1,0)
Connect the points and you have a second line that will never intersect the first because the are parallel:

Happy Calculating, Sher!!!
