Frieds: I have a question, as always I imagine it is quite simple.
 
I have made several functions. I give the following example:
 
newsubstraction[a_List, b_List]:=Module[{k=((b[[2]]+a[[2]])-(b[[1]]+a[[=
1]]))/2},{middle[a]-middle[b]-k, middle[a]-middle[b]+k}]
 
This function takes two lists of the form {a1,b1} and {a2,b2} and returns a list of identical form.  Now, suppose I have an equation with an unknown (of the form {u1,u2}). My question is: how to solve it?
I would like something of the sort:
IMAGINEDSOLVE[newsubstraction[firstlist, UNKNOWN]==secondlist, UNKNOWN]
I would like this IMAGINEDSOLVE to work for newsubstraction and other functions of the same type. Thanks for any help.
