Can you help me to solve this Matrix Transformation problem please?

Question

x-2y+3z=3
2x+y+5z=8
3x-y-3z=-22
Thank You.

Answer 1

Cramer's rule

The equations are x  - 2y  + 3z  = 3 ---> (1)

2x  + y  +5z  = 8 ---> (2)

3x  - y  - 3z  = -22 ---> (3)

Write the equations (1) , (2) & (3) into matrices form AX  = B .

A  is coefficient matrix , X  is variable matrix and B  is Constant matrix.

Solution :
