Answer to Problem 32PPE
Explanation of Solution
Given:
The given matrix equation is
Concept used:
The sum or differences of the any matrix is possible, when the number of elements of both matrices are same. i.e. number of columns are same and number of rows are same.
Calculation:
As the given matrix equation is
Here number of elements in both matrices are same.
Therefore, add the matrix. Now,
On comparing the elements of the LHS and RHS of the given matrix, it is found that
Now, compute the value of
Now, substitutes the value in eq (2), then
Now, substitutes the value of y in eq {1}
Hence, the value of
