# How do you solve 3p - 6 > 21?

Jun 4, 2018

$p > 9$

#### Explanation:

$\text{isolate "3p" by adding 6 to both sides}$

$3 p \cancel{- 6} \cancel{+ 6} > 21 + 6$

$3 p > 27$

$\text{divide both sides by 3}$

$p > 9 \text{ is the solution}$

$p \in \left(9 , \infty\right) \leftarrow \textcolor{b l u e}{\text{in interval notation}}$
