So what I personally would do is try and isolate x by itself! I hate working with fractions, as someone with dyscalculia, so I tend to turn those into decimals, but make sure to check with your teacher because they may not want you to do that (you’ll come into rounding issues and a whole thing with sigfigs which won’t pop up for you until high school chemistry/mathematics.)
Move one of those x’s to the other side, and then get it alone by moving the other “number” without the x! IE Move 2/3 over, then add 2 to the 4 on the other side. I THINK you use the flip of 2/3 when you move it over- but don’t quote me! I’d double check with your notes or teacher on the fractions, I despise them and typically work with decimals in my physics class. I hope I helped a little. :)
