**Reiny**, Sunday, March 21, 2010 at 8:40pmYou are doing nothing wrong.

You are faced with two equations that have no solution.

Graphically, you would have two parallel lines, notice the slopes are the same.

Solving two equations is the same as finding the intersection of their corresponding graphs.

Parallel lines do not intersect by definition.

So just say, "no solution"
