Using matrices solve the system

Question

x-y+z=17
2x+3y+z=8
-4x+y+5z=-2

Answer 1

Given equations are x - y + z = 17 ---> (1)

2x + 3y + z = 8 ---> (2)

-4x + y + 5z = -2 ---> (3)

Solve the equations in Cramers method.

AX = B

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

Solution x   = 7 , y  = -4 and z  = 6.
