I'm going to be using the free open source computer. Ouch! Persistent Morsi s called Maxima for solving these problems. Where there s us to do it with the computer for problem 30 aren't matrix. It is minus 56 1/3 11 6 0 2/3 Who one minus one have minus two. Fifth on converting it. And I believe that maybe that has a zero. Determine it. That's here. That's permanent. Ah, there is the input from line 23. Yep. So no inverse exists for that, mate.
