here are the steps i'd take. if anything's unclear let me know and i can further explain them!
5 - (4/3)x = 2
let's move all numbers and all variables to different sides. remember that we have to change their signs when we move them over.
5 - 2 = (4/3)x
3 = (4/3)x
now we'll divide both sides by (4/3). so, it'll become multiplying it by 3/4.
3 x 3/4 = x
9/4 = x
hope i helped! good luck.
