The question asks,

for matrix A =

1 1 3

3 0 1

2 2 6

, find a vector b such that Ax(x is a vector) = b has no solution.

I found the rref(a) =

1 0 1/3

0 1 8/3

0 0 0

Now to, answer the question,

I gues the equation has no solution if one of the rows has 000 = a nonzero value.

So, is it right to say b is a with a nonzero value on the third row?
