Best ResponseYou've already chosen the best response.0You can't add 3x. Your goal to solve for x is to isolate it. To do so, move the term with a variable to one side and the constant to the other. To do so, subtract both sides by x then subtract both sides by 2 and simplify from there to get x completely on it's own.
