Which best proves why the expressions 4 (x+3)+2x and 6 (x+2) must be equivalent expressions

Step-by-step explanation:

The given expressions are:

and

Taking the first expression, we have

=

=

=

Now, taking the second expression in order to solve it, we have

=

=

which shows that both the expressions are equivalent in nature, thus on solving the given expressions, they comes out to be equivalent.
