Question 43953: Tell whether the systems of equations have only one ordered pair as a solution or not. Also exlpain your answer by telling whether the graphs of the equations are parrallel lines, intersecting lines, or the same line.

x + 2y = 3
x + 2y = 6
Answer by fractalier(6550) About Me  (Show Source):
You can put this solution on YOUR website!
If we subtract these equations
x + 2y = 3
x + 2y = 6
you get
0 = -3
We ask, "When does 0 = -3?"
The answer is never. Thus, this system has no solution and the lines are parallel, an inconsistent system...
