1. Forward elimination changes Ax = b to a row reduced Rx = d: the complete solution is
x=(4,0,0)+c1(2,1,0)+c2(5,0,1)
(a) What is the 3 by 3 reduced row echelon matrix R and what is d?
(b) If the process of elimination subtracted 3 times row 1 from row 2 and then 5 times row 1 from row 3, what matrix connects R and d to the original A and b? Use this matrix to find A and b
