Question 59573
I need to solve the system by graphing: 
x + y = 3...........y = 3-x............1
x + y = -1 ..........y = -1-x

x..................0..........1................5.........etc.........
y =3-x.............3...........2...............-2........etc..
y=-1-x.............-1..........-2................-6.....etc.....
now plot the points . see graph below.


{{{ graph( 500, 500, -10, 10, -10, 10, 3-x, -1-x) }}}

they are 2 parallel lines which do not meet hence no solution.

Thank you,
Ashley
