Question

1. Consider matrix equation Ax=b with (2 4 3 -2 A. Convert the augmented matrix to reduced echelon form without using fractions at any intermediate stage. Clearly indicate the operations used in each step. B. Find the set of all solutions, write the solution in the vector form of x-p+su+ IV C. Two equivalent ways for checking the solutions Method 1: verify that the RREF is correct RREF: Column relations (4b: Columns relations Method 2: verify x in (B) satisfy the system Calculate Ap, Au, and Av to verify that Ap=b:

I understand and got part A and B. I am not sure what to do about Part C. A real in-depth answer with the math worked out would be much appreciated! Thanks!
