If xy + z = x(y + z), which must be true?
a. x = 0; z = 0
b. x = 1; y = 1
c. y = 1; z = 0
d. x = 1 or y = 0
e. x = 1 or z = 0
If xy + z = x(y + z), which must be true?

Given statement:
xy+z= x(y+z)
==> xy+z = xy+xz.
Cancelling xy on both the sides and moving z to other side the equation becomes...
xz-z=0
==> z(x-1) =0
==> z=0 or x=1... Hence E is the answer for the above problem..
Hope it is clear...
