## Homework Statement

Using boolean algebra, verify if the identity is true. Draw truth table to verify answers.

x XOR 1 = x

## The Attempt at a Solution

[itex]x \oplus 1 = x[/itex]

(x’ * 1) + (x * 1’)

(x’ * 1) + (x * 0)

(x’ * 1) + 0

(x’ * 1)

x’

I've proven that the equation is false. How do I draw truth table to prove it? Help appreciated. Thanks.
