(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Decide c, so that A(2)X=b(c) where

x=(x,y,z) and b(c)=(1,c,1)

A(2) is calculated from the previous problem:

"Decide the value on the parameter b so that the following system has solutions

(2, 1,-1,b

1, 2, 2, 2b

1,-1,-3, b+1)

2. Relevant equations

3. The attempt at a solution

Alright, I solved the previous problem that is stated and I got the answer to be b=-1/2

but from that, what do I do? The real question is, what does A(2)x mean? I substitute b for 2?
