`-6x+3y-2z = -21`
`4x+2y+5z = -9`
`-5x+6y+z = -36`

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)` = (,,).
