The property used to arrive at line 2 is the additive property of equalities
The additive property of equalities states that for real numbers if x = y : then x + z = y + z
For example if 2 = 2 , then 2 + 1 = 3
In order to arrive at line 2, x and 2x were added together to arrive at 3x
The distributive property was used to arrive at line. The property states that : x(1 + 2) = x + 2x
