Fill in the blanks with the correct words and match the words with their uses.

Add $9\,\mathrm{m}$ to both sides:

$$2b - 9\,\mathrm{m} + 9\,\mathrm{m} = 3\,\mathrm{m} + 9\,\mathrm{m}$$ $$2b = 12\,\mathrm{m}$$

Divide both sides by 2:

$$b = \frac{12\,\mathrm{m}}{2}$$ $$b = 6\,\mathrm{m}$$

b = 6,m

b = 6 m

Divide both sides by 3:

$$m = \frac{17\,\mathrm{m}}{3}$$ $$m \approx 5.67\,\mathrm{m}$$

\boxed{m \approx 5.67,\
