First is "given", but we don't have to worry about that
Second is "subtraction property" because we subtract 2/3 from both sides
Third is "subtraction property" for similar reasons as before, but we subtract 3x from both sides
Fourth is "division property" because we divide both sides by -1. Note how the inequality sign flips. This is because we divide both sides by a negative number.
The last would be something along the lines of "simplify" or "reduce"
