hi guys , i want to write a complicated differential equation as autonomous equations , is there any method ? i have no idea to overcome it !

It may be possible to introduce a new variable, which will eliminate the time from the equation. For example:
(x' - x)t + x = 0
Let u = xt and the equation becomes
u' = u
If that fails, you can always convert an equation to an autonomous system of two equations in two variables, letting the second variable = time.
