[From: ] [author: ] [Date: 11-07-07] [Hit: ]

......

a. Inconsistent -- no solution
b. Dependent -- infinite number of solutions
c. Consistent -- a single solution

add the equations:

4x = 8
x = 2

2(2) - 3y = 6
-3y = 2
y = -2/3

c. Consistent -- a single solution

c. Consistent -- a single solution
Matrix of coefficients is non-singular.
