We have some number x that we do two things to it in this exact order: divide by 3, add 8.
To isolate x or get it all by itself, we have to undo what is happening to x. We follow the order mentioned above in reverse so that we undo everything properly. Undo the "add 8" by subtracting 8 from both sides. Then you undo the "divide by 3" by multiplying both sides by 3. Check out the attached image for details and the steps on how to solve.
