Answer: b = 4/3 or b = 1.3333333
Explanation: You simplify 4/6 to 2/3 by dividing by 2. Then, you have b - 2/3 = b/2, so you then add 2/3 to both sides since its a negative in the equation, and you get b = b/2 + 2/3. After that, you subtract b/2 from both sides and get b/2 = 2/3, then you multiply both sides by 2, and get b = 4/3 for your answer.
