**Steve**, Monday, November 7, 2011 at 11:44amIf you're trying to find k, why divide by 0? You divide by the coefficient of k, which is -1.

-k/(-1) = 287.658/(-1)

k = -287.658

Or, to avoid any division at all, just swap sides of the = sign:

-k + k = 287.658 + k

0 = 287.68 + k

-287.658 = 287.658 + k - 287.658

-287.658 = k

You could probably have done that in your head, but I wanted to show the underlying machinery that makes it all happen.
