Step by Step Solution

Step 1: Consider the matrices and perform the addition operation.

If A and B are the matrices of same size, then, the sum of matrices is,

a11a1m an1anm+b11b1m bn1bnm=a11+b11a1m+b1m an1+bn1anmbnm

The given matrices are,


Perform the addition operation.



Step 3: Consider the matrix and perform the product operation.

If A is an n×m matrix with row vectors ω1,......,ωn and x is a vector in m then,

Ax=- ω1 -- ωn -x=- ω1.x -- ωn.x -

The given matrix is,


Here A is 1-12345 and x is 9

Perform the row column operation.
