From a) to b), you expand the brackets, which is -6x+8.
From b) to c), you bring -6x to the other side of the equation.
By bringing it to the other side, -6x becomes +6x.
You then do 5x+6x, which is 11x.
From c) to d), you bring +2 to the other side of the equation.
By bringing it to the other side, +2 becomes -2.
You then do 8 - 2, which is 6.
From d) to e), in order to get x by itself, you divide it by 11, hence 6/11.
This makes the equation become x = 6/11.
Sorry if that made no sense
