Anyone...help? Click to expand... You must have made a typo. the only solution to that is x=0 y=0. Last edited: 17 Feb 2011

Click to expand... (x,y) = (0,0) is only one solution. Both equations given are the same equation. Hence 1 equation + 2 variables gives infinite solutions. The solution is a line going through (0,0). *prepares for a really obvious mistake to be shown* edit: This is if you ignore the very small rounding error. Last edited: 17 Feb 2011
