use matrices to solve the following system

Question

2x-y-z=-3
x-2y+3z=6
x+y+z=6
use matrices to solve thank you.

Answer 1

Given equations 2x - y - z  = -3 --->(1)

x - 2y + 3z  = 6 ---> (2)

x + y + z  = 6 ---> (3)

Convert the equations in matrix form AX = B.

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

Now solve the equations in Cramer's maethod.

Solution
