use cramers rule to solve

Question

5x-4y+z=17
x+y+z=4
-10x+8y-2z=11

Answer 1

Cramer's rule :

The system of equations are

5x - 4y + z = 17       ---> (1)

x + y + z = 4           - --> (2)

- 10x + 8y - 2z = 11  ---> (3)

Write the system of equations into matrices form AX  = B, where A is coefficient matrix, X  is variable matrix and B  is constant matrix, and solution is

.

Since , the system of equation has no solution.
