For $\displaystyle 3$, solve $\displaystyle x\begin{Bmatrix}0\\ 1\\ 2\\ 4\end{Bmatrix}+y\begin{Bmatrix}2\\ 0\\ -1\\ 1\end{Bmatrix}=\begin{Bmatrix}a\\ b\\ c\\ d\end{Bmatrix}$
For $\displaystyle 4$, solve the system of equations:
$\displaystyle \left\{\begin{matrix}-x+0y+3z=0\\ 0x+y+z=1\\ -x+y+kz=k\end{matrix}\right$.
