Solve using Cramer's Rule.

Question

7x + 6z = 48
4x + 6y + 6z = 42
8x - 8y = 32

Answer 1

Given equations are 7x + 6z  = 48 ---> (1)

4x  + 6y  + 6z  = 42 ---> (2)

8x  - 8y  = 32 ---> (3)

Convert the equations in to matrix form.

AX  = B.

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

Solve the equations in Cramers method.
