In seperation of variable method, we first write the equation in multiplication of seperate function than we take one variable to one side and other variable to other side and solve the equation. In the given question, x2 and e-t are two different functions so we will take x variable to right hand side and t variable to left hand side and integrate both sides to get the solution.
feel free to comment if you have any doubt.
