A= [ 2 -3] B= [4 ]

[ 1 5] [2 ]

(theres a blank space between the 4 and the 2)

**Reiny**, Thursday, July 23, 2009 at 6:37pmI found the inverse of A to be

5/13 3/13

-1/13 2/13

so

A^{-1}A X = A^{-1</sup B X = │ 5/13 3/13││4│ │-1/13 2/13││2│ = │2│ │0│ } - Finite Math -
**Reiny**, Thursday, July 23, 2009 at 7:23pmthat doesn't look like I intended.

let's try that again

so

A^{-1}A X = A^{-1}B

X =

│ 5/13 3/13││4│

│-1/13 2/13││2│

=

│2│

│0│
