Hey elorabees.
Hint: Try using De-morgans laws on a few of the terms.
Okay, but what can I do with xz'? I don't know what to do when we have a variable with a complement and a variable without a complement together?
I just reduced this part:
x'y'+xz'+yz=x'+y'+xz'+yz=(x'+x)(x'+z')+(y'+y)(y'+z )=(x'+z')+(y'+z)=x'z'+(y'+z) , Can we get y'z from that? and can you tell me if that is right?
Just as a hint for these problems, you can double check your work by creating a truth table consisting of 0 and 1 for all variables to check whether two statements are equivalent. I recommend you do this to check your own answers.
