Find matrix A. `A+I_3=[[1,3,4],[-1,1,3],[-2,-3,1]]`

" If matrix "A=[[1,1,3],[1,3,-3],[-2,-4,-4]]" then find "A^(-1)

1.Find the rank of the matrix [[1,-2,3,4],[-2,4,-1,-3],[-1,2,7,6]]

Find the inverse of A=[[1,3,3],[1,4,3],[1,3,4]] and B = [[1,2,3],[1,1,5],[2,4,7]] then, find a matrix X such that XA = B .

Find the rank of the matrix [[1,-2,3,4],[-2,4,-1,-3],[-1,2,7,6]]

Find the Rank of the matrix A = [[1,4,5,2],[2,1,3,0],[-1,3,2,2]]

Find the rank of matrix [ [1,1,-3,2],[2,-1,2,-3],[3,-2,1,-4],[-4,1,-3,1] ]

Find the rank of the matrix [[2,1,-1,2],[1,3,2,-3],[-1,2,1,-1],[2,-3,-1,4]]

find the rank of matrix A=[[2,-1,-2,-4],[1,3,-1,-1],[3,1,-1,-1],[6,3,0,-7]]

Find a matrix A ,if A+[[2 ,3],[ -1, 4]]=[[3,-6],[-3, 8]]

Show that the matrix, A=[[1, 0,-2],[-2,-1, 2],[ 3, 4, 1]] satisfies the equation, A^3-A^2-3A-I_3=O . Hence, find A^(-1) .
