I have used matrix method of solving simultaneous equation on these x + y + z = 5 2x  y + 3z = 16 3x + 2y  z = 3. All the results I get when substituted into the original equation does not tarry with what is on ground, until I used the old traditional method and got x = 9, y = 2, z = 12, and substituted the values to the original equations and it worked. Now my take is that you cannot use matrix method or Cramer rule to solve the equation. If I am lying, prove me wrong. Am ready to learn maybe if I missed something along the line when solving.
