@Guesswhoitis. Good idea. I have acted on it.

comment intermediate steps of a Mathematica operation
@wally. Mathematica doesn't perform any intermediate steps such as you show when it does arithmetic. It could be programed to demonstrate the steps of school arithmetic, but would not be a trivial project. You might challenge followers of this site to produce such code. However, you will have to reword your question to make it clear that's what you want. Can't say whether or not you will get any takers.

comment Error in the solving of the simultaneous Ordinary Differential Equation
@AshishkumarAshishkumar. I think you need a formulate a better model. Since I have no idea of what kind of physical system you are studying, I can't make any really helpful suggestions. Probably couldn't even if you described the system, because it's not likely I would have expertise in your area. Besides, formulation of a model from observational or theoretical considerations is not on-topic for this site. Sorry.

comment Error in the solving of the simultaneous Ordinary Differential Equation
@AshishkumarAshishkumar. I mean that all three of equations I show in my answer are considered as part of your system by DSolve, not just the first two. DSolve has no concept of constraint. The message you are seeing is DSolve's way of telling you it can not solve your system as you are formulating it.
