1. The problem statement, all variables and given/known data How would I solve a two-level system such as this: [tex]y_1'=-ay_1+by_2[/tex] [tex]y_2'=-ay_2-by_1+c[/tex] where a b and c are constants. 2. Relevant equations Laplace transform 3. The attempt at a solution I guess my question is what method would I use to solve this? As in should I solve for y1 in terms of y2 and then plug that back into the second equation? Not too sure about the approach.
