Solve x + 3y + z = 1, 2x – y – z = 6 and 5x + y + z = 1 using matrices.

Question

Solve x + 3y + z = 1

2x – y – z = 6
5x + y + z = 1 
using matrices.

Can you help me figure out this matrix?

 

Answer 1

Gven equaions are x+3y+z = 1

2x-y-z = 6

5x+y+z = 1

To solve the equations we use here carmers method.

AX = B

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

Solution of given equations x = 1, y = 2,  z = -6.
