What do you mean by "solving a boolean expression"? – JRN Jan 26 '16 at 10:17

Hint:
$LHS=AB+ABC+ABC=AB+ABC=AB(1+C)=AB.1=AB=RHS$
$LHS=Z(Y+Z)(X+Y+Z)=Z(Y+Z+0)(Y+Z+X)=Z(Y+Z+0.X)=Z(Y+Z)=(Z+0)(Z+Y)=Z+0.Y=Z=RHS$
This assumes that you are familiar with the various properties and identities of Boolean Algebra.

It means "Left Hand Side" and "Right Hand Side". I used it to denote the two sides of the equality you need to prove. So getting LHS=RHS means the equality has been shown. – GoodDeeds Jan 26 '16 at 09:22
