Let me just cross multiply. So let me multiply both sides of this equation by 20 and y, just so that I don't have as many things in the denominator. So on the left-hand side, it simplifies to 20x. I don't want to write over it. Well, I'll just write 20x. And on the left-hand side, it is 20x. And then on the right-hand side, let's see, this cancels with that.
