Question 327904: solve by elimation
4x-8y=5
4x-8y=6
I know I must multiply to make one of the equations the opposite of the other, but I am not sure which or by what number. I am thinking (-1) and the first equation. but that is just going to bring the equation to
-4x+8y=-5
4x-8y=6
which still doesnt work..So I am all sorts of confused, if you can please help me out and explain..Much appreciated!!!THANKS A BUNCH!!!

You can put this solution on YOUR website!
solve by elimation
4x-8y=5
4x-8y=6
---------------
If we assume the x's and the y's have the same value respectively,
we can subtract the 1st equation from the 2nd to get:
0 = 1
------
That is a contradiction.
That result tells us the x's and the y's do not have the same meaning
in the two equations.
-------
Conclusion: No solution for the system of equations.
