## Homework Statement

Hey guys,

Can someone please explain how the following circuits that I attached are equivalent? I'm not seeing that they are when I develop equations for the output Z.

For the first one I get Z=Q1+Q2=(Q1'+Q2')+(XQ2')'=Q1'+Q2'+X'+Q2

For the second image I get Z=Q2'+Q1=(XQ2')'+Q1=X'+Q2+Q2+Q1'

so I must be messing up somewhere and not catching it.

Any suggestions?

Thanks!
