Question
Consider the following two matrices: A = [1 -1 1 0 2 2 1 1 3], B = [1 -1 1 0 2 2 1 1 2]. For each matrix, compute its inverse (it they exist). Assume you are given a 4 by 4 matrix A with real entries. (a) What matrix multiplies A from the left to perform the following row operation: swap rows 1 and 2? (b) What matrix multiplies A from the left to perform the following row operation: multiply row 2 by 3 and add to row 4? (c) What matrix multiplies A from the right to perform the following column operation: swap columns 3 and 4? (d) What matrix multiplies A from the right to perform the following column operation: multiply column 2 by -3 and add to column 4?Explanation / Answer
Since determinant value is 0 => Inverse of the matrix is not possible
b)

Dear Student Thank you for using Chegg !! A = 1 0 1 -1 2 1 1 2 3 det(A) = 0
