Your equations are linear with constant coefficients. I would handle either the following ways
1. Apply the Laplace transform to the equations - this will transform the problem to solving algebraic system of equations or
2. Let the solution be x1
. Substitute this assumption and you can determine r, q1
from eigenvalue-eigenvector equation.
