Actually I don't understand how this actually works. A*x returns a list, as map() does, but A*x won't work while you're construction does. Why?

I know I can solve a system of equations by inputing independently each equation in a same solve() expression using the syntax solve([[exp1],[exp2], ... [expn]], x1,x2, ... xn), but what should I do if, having defined a matrix A and two columns vectors x and y, I want to express the system of equations as A*x == y?

Each instance of A[i] * x returns a list, that is (of course) not treated as a valid argument for an equation in solve(). How could I "tranform" that list in order to use it with solve()?
