Okay, so I'm stuck at a step of a much bigger problem where I have to simplify a boolean function. 1. The problem statement, all variables and given/known data Here is where I'm stuck, I have to change the left hand side to the right hand side. How do I prove this with the rules of boolean algebra? CA + CB + B'A = CB + B'A 2. Relevant equations 3. The attempt at a solution The above is as far as I've gotten (as I said, this was taken from a bigger problem). Can someone please show me the steps that will change the left hand side of the equation to the right? According to truth tables, they are infact equal.
