# How do you solve and graph P - 1.5 < 1.5?

Aug 24, 2015

Solve as if you were solving an equation. Write a circle on the hash mark representing the number $3.0$ on the number line. Shade the entire number line to the left of the number $3.0$.

#### Explanation:

$P - 1.5 < 1.5$

Add $1.5$ to both sides of the inequality.

$P < 1.5 + 1.5$$=$

$P < 3.0$

On a number line, circle the hash mark representing $3.0$. Then shade the line to the left of $3.0$ all the way to the arrow. The interval notation for this inequality is $\left(- \infty , 3\right)$.
