comment Simplify a boolean algebra expression: xy + xz' + x'yz
$$(xyz+xyz')+(xyz'+xy'z')+x'yz$$ $$=xyz+(xyz'+xyz')+xy'z'+x'yz$$ $$=xyz+xy'z'+x'yz$$, you made an error

comment Simplify a boolean algebra expression: xy + xz' + x'yz
$x=1,y=1,z=0$: then $xy+xz'+x'yz=1+1+0=0$ and $xz'+yz=1+0=1$. These terms are not equal.
