Follow-up Question
I'm still confused on your solution could you go over each step again but in more detail. Like for the reactions are you finding the reactions at A and G. You wrote reaction at A and B so I'm a little confused. If so how did you know to take the reaction at those points and how did come about that equation for the reactions. How does x vary from 0 to 24 and 24 to 36.
