$e^{3x}dy=-dx$

Learn how to solve differential equations problems step by step online. Solve the differential equation dx+e^(3x)dy=0. We need to isolate the dependent variable y, we can do that by subtracting dx from both sides of the equation. Group the terms of the differential equation. Move the terms of the y variable to the left side, and the terms of the x variable to the right side. Integrate both sides of the differential equation, the left side with respect to y, and the right side with respect to x. Solve the integral \int1dy and replace the result in the differential equation.
