The authors present a method for solving the differential equation
y(n) + a1y(n-1) + … + an-1y' + any = f(x),
where a1, …, an are constant. Their method can also be applied to solve certain equations that can be reduced to linear equations with constant coefficients by a change of variables. Finally, the authors show how second order equations with variable coefficients can be modified to find the general solution of
y'' + a1y' + a2y = f(x)
from a single solution of
y'' + a1y' + a2y = 0.
