Just wanted to say thanks for your help, I have 1 more question.


Matrix A:
\left(
    \begin{array}{ccc}
      1 & 2 & 1\\
      2 & 1 & 2\\
      1 & 1 & 1\\
      c & 2 & 4\\
    \end{array}
  \right)

and Matrix B:

\left(
    \begin{array}{ccc}
      1\\
      1\\
      b\\
      2\\
    \end{array}
  \right)

I combined these 2 matrices and did row reduction.

I got up to:

\left(
    \begin{array}{cccc}
      1 & 2 & 1 & 1\\
      0 & 1 & 0 & 1/3\\
      0 & 1 & 0 & 1-b\\
      0 & 2(1-c) & 4-c & 2-c\\
    \end{array}
  \right)

I wanted to know for what value of B will any solutions be possible.
Thats all.

New questions need to go in new topics for future reference. Topic split.
