What is the solution to the system of equations 4x-3y+5z=7, -6x-2y+3z=4 and 9x+3y-2z=-10

Question

Can someone help me finish this system?  I've gotten into some pretty hairy numbers and am not sure if i'm on the right path.

4x-3y+5z=7

-6x-2y+3z=4

9x+3y-2z=-10

Answer 1

Given equations are 4x-3y+5z = 7

-6x-2y+3z = 4

9x+3y-2z = -10

To solve the given equations using carmers method.

AX = B

When A is coefficient matrix, x is variable matrix, B is constant matrix.

Convert the equations into matrix form.
