An augmented matrix is given as- a11=2 a12=3 a13=4 b₁=9 a21=5 a22=-2 a23=2 b2=-1 a31-4 a32=6 a33=5 b3=-3 You normalize the first row and performed the following operations: R₂ R2-a21 R1 R3'=R3-a31*R₁ Then you normalized the second row and performed the following operations: R₁"=R₁-a12 R₂ R3"=R3-a32*R₂' What is the new value of a13? Write your answer in two decimal places.
