Quick question about simplifying a differential equation?

In summary, a differential equation is a mathematical equation that relates a function with its derivatives, describing the change in a variable over time or space. To simplify a differential equation, techniques such as substitution, separation of variables, and transforming the equation into a more manageable form can be used. It is important to simplify a differential equation to make it easier to solve and understand, and to find the general solution which can then be used for specific problems and predictions. Some common types of differential equations include linear, separable, exact, and homogeneous equations, with different classifications based on order, degree, and number of variables. Differential equations can be solved analytically using algebraic manipulation or numerically using algorithms and computers.

I have solved this equation but I am just not quite sure why this final result is the way it is.

[itex]\frac{2e^{t}+C}{e^{t}} = 2e^{-t} + C[/itex]

Why is it [itex]e^{-t}[/itex] when its simplified ?

uhhh, how did you get that?

shouldn't it be...
[itex] \frac{2e^{t}+C}{e^{t}} [/itex]
[itex] = 2 \frac{ e^{t} }{ e^{t} } + \frac{ C }{ e^{t} } [/itex]
[itex] = 2 + C e^{-t}[/itex]

I also got e^(-t) = -1
