y' +3y =e^(-t) y(0)=-1/2 y=(e^-t)/(2-e^-3t)

I can not get this one to work out
 
Re: verify by differentiation

What did you try?. What integrating factor did you use?.

How so? You differentiated the given expression for y (to find y'), plugged y and y' into the given differential equation, and... then what?

Please be complete. Thank you! :D
