b=0, then Ax=0 has infinitely many solution if det(A)=0

b<>0 then it can have zero or an infinity of solution, depending on the determinants : [tex] det(b|_nA) [/tex]

where [tex] b|_nA [/tex] means : the nth column of A is replace by b.

So the answer is "true and false" because you don't specify enough the question.

or you might say the question is meaningless since you do not quantify the letter "b".
