# 4 7 − 5 2 . Matrix Equations : Solve the matrix equation for the unknown matrix X, or show that no solution exists, where A = [ 2 1 3 2 ] , B = [ 1 − 2 − 2 4 ] , C = [ 0 1 3 − 2 4 0 ] 2 X + C = 5 A

To determine

To find:

The value of unknown matrix X satisfying matrix equation 2X+C=5A, if solution exists, where A= and C=.

Explanation

Approach:

Two matrices A and B can be multiplied if they satisfy the condition that the number of columns in A is same as the number of rows in B.

Two matrices A and B can be added or subtracted only if they have same dimension.

Calculation:

A= and C=

In order to be added to the matrix C, matrix X must be of the dimension 3×2.

Let, X=[x1x2x3x4x5x6]

2X+C=5A2[x1x2x3x4x5x6]+[013240
