What is the justification for each step in the solution of the equation?

Given
Step 1: They multiplied 3 on both sides of the equation to get rid of the denominator (you can do this because the denominators were the same number, which was 3)
Step 2: They distributed 6 into (x + 2)
Step 3: They added 1 on both sides
Step 4: They subtracted 6x on both sides to get "x" on one side of the equation
Step 5: They divided -4 on both sides to get "x" by itself
