I need some help...i need a solver using the Runge-Kutta method adaptive size control, to solve a sytem of 5 diff eq's, all of them are interlinked...

 

And 

 

Say that dsolve numeric produces a results, called Solution, Now ex  solution(0)=1, and in general solution(t) can be evaluated, now, i want to use this, in E(t)=2*solution(t), in a plot, thus...

 

plot(E(t),t=0..100,....), but returns the error....

 

Error, (in E) invalid input: solution expects its 1st argument, x_rk4step, to be of type realcons, but received t


How Can i solve this.......
