# How do you solve and graph b – 4 < 2.5?

Jul 15, 2015

$b < 6.5$
Draw a number line and mark everything to the left of $6.5$ as included in the solution set.

#### Explanation:

Given $b - 4 < 2.5$

You can add the same amount to both sides of an inequality without effecting the orientation of the inequality.

So, by adding $4$ to both sides we get
$\textcolor{w h i t e}{\text{XXXX}}$$b < 6.5$
