##### Exercise3

For both parts of this exericse, give a written description of sets of the vectors $$\bvec$$ and include a sketch.

1. For which vectors $$\bvec$$ in $$\real^2$$ is the equation

\begin{equation*} \left[\begin{array}{rr} 3 \amp -6 \\ -2 \amp 4 \\ \end{array}\right] \xvec = \bvec \end{equation*}

consistent?

2. For which vectors $$\bvec$$ in $$\real^2$$ is the equation

\begin{equation*} \left[\begin{array}{rr} 3 \amp -6 \\ -2 \amp 2 \\ \end{array}\right] \xvec = \bvec \end{equation*}

consistent?
