expand

- \frac{1}{3} (12 - 6 + 15 x)

- 2 - 5 x

Solution steps

- \frac{1}{3} (12 - 6 + 15 x)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

- \frac{1}{3} (12 - 6 + 15 x) = - \frac{1}{3} \cdot 12 - \frac{1}{3} (- 6) - \frac{1}{3} \cdot 15 x

= - \frac{1}{3} \cdot 12 - \frac{1}{3} (- 6) - \frac{1}{3} \cdot 15 x

Simplify

- \frac{1}{3} \cdot 12 - \frac{1}{3} (- 6) - \frac{1}{3} \cdot 15 x : - 2 - 5 x

= - 2 - 5 x
