Solve the system using Cramer's Rule.

`-5x+5y+6z = -20`
`4x-3y-4z = 12`
`-x+2y-2z = 12`

Find the determinant `D` (denominator).
`D` =

Find the determinant `D_x` associated with `x`.
`D_x` =

Find the determinant `D_y` associated with `y`.
`D_y` =

Find the determinant `D_z` associated with `z`.
`D_z` =

The solution is `(x,y,z)` = (,,).
