Exercise 3
For both parts of this exericse, give a written description of sets of the vectors \(\bvec\) and include a sketch.

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?
