Instead of writing a y, I'm gonna write it all in terms of x. So is that equal to four times x to the fourth, because x to the fourth is the same thing as y, divided by x. And so let's see, x to the fourth divided by x, that is going to be x to the third. And so you will indeed get four x to the third is equal to four x to the third. So check, this is a solution. So is a solution. It's not necessarily the only solution, but it is a solution to that differential equation.
