The valid manipulations are to add the same amount to each side or multiply each side by the same amount. In your equation
I want to put off working with fractions as long as possible so I would multiply both sides by 2. The equation then becomes
Next simplify the right side to get
The goal is to have no "b term" on the right side so add 3b to each side to get
