Question 43954: Tell whether the systems of equations have only one ordered pair as a solution or not. Also explain your answer by telling whether the graphs of the equations are parrallel lines, intersecting lines, or the same line.
x + 2y = 3
2x + 4y = 6

You can put this solution on YOUR website!
Well if you multiply the first equation by two, look what you get
2[x + 2y = 3] =
2x + 4y = 6
Thus these two equations represent the same line...infinite solutions and a dependent system...
