 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!!!Answer by stanbon(57387)   (Show Source): 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. ======================================================== Cheers, Stan H.
