Find a constant matrix such that the above system is equivalent to
My first thought was to find a solution to . Taking the characteristic polynomial as , I get . Not really sure what to do at this point, however. Another way to solve this might be first to replace v' in the second equation with w to get but I'm not sure where to go from there either.

Step 1
(I'm assuming here that you meant instead of ; in the latter case, would just be the identity matrix.)
If you replace v' with w in the second line of your equation and isolate each equation for v' and w', you get:
Step 2
Now all you have to do is find a matrix of coefficients a through d such that:
For this matrix to correspond to your set of equations, it must be the case that , and .
