And we get two is equal to c times e to the third power, three times one. And so to solve for c, I can just divide both sides by e to the third, and so I could, or I could multiply both sides times e to the negative third, and I could get two e to the negative third power is equal to c. And so let's now substitute it back in. And our particular solution is going to be y is equal to c. C is two e to the negative third power times e to the three x. Now I have, I'm taking the product of two things with the same base. I can add the exponents. So I could say y is equal to two times e to the three x, e to the three x, and then I'll add the exponents to three x minus three. And there you go.
