Linear algebra need to solve d,e,f,g,h You are given the following set of 5 vectors from R4: 4. 7,s} = {<2,-3,4,-5),(1,-2,2,-3),(1, 2, 2, 1), (5,-3, 7,-6), (6, 7, 3, 7)}, S and 11,15, 1, 18) e R4. Form the augmented matrix a. Next, we will find the rref of the augmented matrix. Take turns going around the group in deciding what row operation to do next. All members of the group should do that operation. Check each other's work. Do...
