I apologize in advance for what many of you will find to be a simpleton question.

Would someone mind walking me through the algebraic manipulation in this problem? I completely understand how to get to:

e^-lamda * lamda^2 / 2 = 3e^-lamda * lamda^4 / 24

Unfortunately, I'm not following how that gets simplified to lamda = 2.

Thanks for any help, I really appreciate it!
