You could put the constant on that side as well. It doesn't matter, all the constants could kind of merge into one. Now, this is, we've gotten pretty far. We want to solve the particular solution. Right now, we only have this constant, and we also haven't written W as a function of t just right yet. It's kind of a, they're implicitly expressed, this is more of a relationship than a function right now. So the first thing we can do is try to solve for C. We're told in the problem, we're told in the problem that W of zero is equal to, W of zero is equal to 1,400 tons.
