g'day,
You can do a lot of automation.
Simply define a variable to be the solution to one step, i.e.
i=Det[{...}] then j=function[i] etc. until you're done.
Put it all in one cell, and shift-enter will evaluate it all and give you the final result from the given input.
Note that some solutions will be presented in different forms such as
k->{{the_value_you_actually_want},{another_equivalent_solution_with_opposite_signs},...}
rather than
k=the_value_you_actually_want .
So you need to "unwrap" the solutions given to you to get to the good stuff, remembering that Mathematica uses list structures.
i.e. if you've solved an equation for the variable ChaseAndEat and gotten the solution
SoManyOptions->{{"cat","mouse"},{"T Rex","human"}}
then ChaseAndEat has a structure just like a list, but with Head set to Rule, instead. Have a look at FullForm[your_intermediate_solution] to see this in your case.
So if the first solution will always be valid, and you're always happy to plug it into the next step then ChaseAndEat[[2,1]] ({"cat","mouse"})will be the appropriate argument for the next function in this example. If you just want the "mouse" then ChaseAndEat[[2,1,2]] would have selected it, for example.
cheers,
