If 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.
