For this case we solve the following equation:
[tex]3 (x + 10) + 6 = 3 (x + 12)[/tex]
We apply distributive property to the terms within parentheses:
[tex]3x + 30 + 6 = 3x + 36[/tex]
We add similar terms:
[tex]3x + 36 = 3x + 36\\36 = 36[/tex]
Since 36 equals 36, then the equation will always be true for any value of x.
