This isn't really a question, I just need help on explaining Cramer's Rule.

Question

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

Answer 1

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

3x  + 2y  + 4z  = 5 --->(2)

-4x  - y  + 2z  = 4 ---> (3)

Write the equations into matrices form AX  = B .

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

Now solve the equations in Cramer's rule.

Solution
