linear algebra question pls helpa) What conditions must the entries of b satisfy in order for Ax = b to have a solution?b) What is the nullspace of R? (Write it in terms of a basis.)c) Assuming that the conditions in (a) are satisfied, what is a particular solution xpAx = b? (You can set the free variables to anything when finding xp; but please set themto zero here.)d) What is the full solution to Ax = b?There are two good ways
