Answer 5

yes! that one.

Answer 6

given a set of equations:
we strip the variables and use only the coeffs for our column vectors in the matrix, does that make sense?

Answer 7

2x+3y=9
4x+5y=3

\begin{pmatrix}2&3&9\\4&5&3\end{pmatrix}

Answer 8

if there is a variable missing from one equation to the next, you use zero "0" for its entry

Answer 9

2x-y=3
y=4

\begin{pmatrix}2&-1&3\\0&1&4\end{pmatrix}

Answer 10

the solution to the system is just the row reduced form of the augmented matrix; the RREF command if you can find it
