What is the justification for this:
=(x)+(x) =x+x =x
?

Starting with the given:
4×6=x+(x+x)

Work within PARENTHESES first.
(x+x) is handled as combining like-terms of x. HOW MANY x?

The entire right-side member has only some terms of x. Still you combine like-terms of x.
x+x+x, the parentheses here not serving any other needed purpose. HOW MANY x?
The entire right-side member is 3x.
