<PRE><B>Question 186570</B>
solve the system of equations using matrices( row operations). if the system has no solution, say that it is inconsistent
----------- 
1/2x + y= -2
x    - 2y= 8
-------------
Coefficient matrix (A):
[1/2....1]
[1.....-2]
---------------
Constant matrix (B):
[-2]
[ 8]
----------------------
Multiply: [A]^-1[B] 
= [ 2]
  [-3]
===============
