This might be a dumb question, but in my Algebra book, for the problem:(adsbygoogle = window.adsbygoogle || []).push({});

Solve R = 3(a + b) for b

I came up with: [tex]\frac{R}{3} - a = b[/tex]

The book has the answer listed as: [tex]\frac{R-3a}{3} = b[/tex]

Which one is simplified? The book tells us to always give your answers in simplified form. To me, my answer seems more simplified than the book's answer since I removed the 3 in the numerator. Is it? Or is there some reason the answer should be left as the book has it?

Thanks,
