      The Laplace Transform of a System 1. When you have several unknown functions x,y, etc., then there will be several unknown Laplace transforms. 2. Transform each equation separately. 3. Solve the transformed system of algebraic equations for X,Y, etc. 4. Transform back. 5. The example will be first order, but the idea works for any order.
