I need help with usings Cramer's Rule. The question is: Solve the following system of equations using Cramer's Rule.

Question

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

Answer 1

Cramer's rule

The equations are 2x + 4y - 3z  = 2 ---> (1)

2x - 2y + 3z  = 3 ---> (2)

3x - 4y  + 5z  = 4 ---> (3)

Write the equations (1) ,(2) & (3) into matrices form AX  = B .

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

Solution :
