Elementwise =

A:=Matrix([[1,2],[2,3]]);
B:=<x1,x2>;
C:=<c1,c2>;
#Using elementwise equality:
eq:=A.B+C=~<0,0>;
eq[1];
eq[2];
#Alternatively:
LinearAlgebra:-GenerateEquations(A,[x1,x2],-C);

If I may mention one more variant,

restart:

A:=Matrix([[1,2],[2,3]]):
B:=Vector([x1,x2]):
C:=Vector([c1,c2]):

Equate( A.B+C, Vector([0,0]) );

           [x1 + 2 x2 + c1 = 0, 2 x1 + 3 x2 + c2 = 0]
