Given matrix A below, and that A = B, find the value of the elements in B.

A =
9 −2 3
2 17 0
3 22 8
b11 =
9

b12 =
17

b13 =

b21 =

b22 =

b23 =

b31 =

b32 =

b33 =

Respuesta :

The value of   Matrix B = [tex]\left[\begin{array}{ccc}9&17&3\\2&17&0\\3&22&8\end{array}\right][/tex]

Given : Matrix A = Matrix B

matrix A=      [tex]\left[\begin{array}{ccc}9&-2&3\\2&17&0\\3&22&8\end{array}\right][/tex]

The matrix A=      [tex]\left[\begin{array}{ccc}9&-2&3\\2&17&0\\3&22&8\end{array}\right][/tex] (according to the question)

Since it is given A=B

and substituting the given values of elements of B

matrix B=[tex]\left[\begin{array}{ccc}9&17&?\\?&?&?\\?&?&?\end{array}\right][/tex]

According to the property of equality of matrices,

When the matrices are given to be equal, their corresponding elements are also equal

so

b13 = 3

b21 = 2

b22 = 17

b23 = 0

b31 = 3

b32 = 22

b33 =8

Substituting the found out values in place of the question marks,

Matrix B = [tex]\left[\begin{array}{ccc}9&17&3\\2&17&0\\3&22&8\end{array}\right][/tex]
