You need to be a bit more specific on the x2. Don’t know if you mean 2x or if you’re saying x squared but I’m assuming 2x so in that case you add the like terms. 4x+2x+2x+x=9x then add the 2 9x+2 is your answer. If you were solving for x and you had an equal sign instead of the addition then your answer would be 9/2 or you could simplify that of course.
