Question

medals rewarded!
Use Cramer’s rule to solve the system of equations.
x+4y-3z=9
-4x+8y-3z=36
4x+3y-3z=-3

Answer 1

this takes work
lots of work
if you only want the answer, ask wolfram

Answer 2

i will be happy to show you how to do it in wolfram if you like

Answer 3

This is a pathetic one.
Put this in a 3X3 determinant called A
[1 4 -3] = [9]
[-4 8 -3] = [36]
[4 3 -3] = [-3]
then,

x = det (Ax) / det(A). det (Ax) is where you put the right hand determinant in the x column
and so on.

ok, I'll try
