: Hi,
Could someone please answer this. Thanks
Which system(s) of equation has no solution?
1. y = 3x - 1 and y = -3x +1
2. y = 1.5x-2 and y = 3/2x + 2
3. x+y = 1 and y = -x +3
4. 2x + y = 4 and 2y = 4x + 2 This question is from textbook pre algebra

Answer by stanbon(75887) About Me  (Show Source):
You can put this solution on YOUR website!
3. x+y = 1 and y = -x +3
This pair of equations has no solution.
Putting them in the same form you get:
y=-x+1 and y=-x+3
These two lines are parallel.
There is no common solution.
