How do I solve this with the elimination method?
5x10y=4
5x10y=5
I need x=, and y= to get an ordered pair, but every time I mult. by a neg, everything goes away instead of just one variable! please help!

You 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"
