Hi,I am hoping someone can help me solve these questions:

thanks

let Ax=b be a consistent linear system,with b ≠0

i) show that the set of solutions to the system is the set of vectors {xo+x such that x is an element of NullA, where xo is any solution to Ax=b

ii) suppose that the dimension of Null(A) is zero. How many solutions are there to Ax=b?Explain..
