Question 243410: Solve the system of equations by graphing. x+y=4, x+y= -4

You can put this solution on YOUR website!
x+y=4, x+y= -4
both lines have slope -1 and different intercepts (+4 or -4)
This means that these lines are parallel or do not intersect.
As a result, this system of equation does not have any solution.
