The solution is
y(t) = a*e^t + b*e^(5t)
where "a" and "b" are constants that depend on the values of the initial conditions. b = (y''(0) - y'(0))/20
a = y'(0) - 5b
y(t) = a*e^t + b*e^(5t)
where "a" and "b" are constants that depend on the values of the initial conditions. b = (y''(0) - y'(0))/20
a = y'(0) - 5b
