Hello there !

I'm currently working on a project and I have a simple problem that I can't solve.

I've solved an equation system and I get an answer which looks like G := {A=exp1,B=exp2}  (exp stands for expression)

I would like to assign exp1 and exp2 to my variables : A:=exp1 & B:=exp2

How can I manage to get that ? 

Thank everyone :)
