b)

To solve the equation , start by getting all terms involving on one side and constants on the other. You can add to both sides, resulting in . Next, add to both sides to isolate the term with : . Finally, divide both sides by to get . Don’t you just love when equations unravel themselves nice and tidy?

When tackling equations like this, a common pitfall is forgetting to move all terms to one side before isolating the variable. This can lead to confusion and mistakes. Always double-check your steps, and don’t hesitate to simplify as you go! It’s like tidying up your room—everything in its place makes it easier to find what you’re looking for.
