# How do you solve and graph 2x+9<16?

May 7, 2018

$x < \frac{7}{2}$ or $x < 3.5$

Plot the graph of x=3.5 with dotted line and shade the area of $x$ less then 3.5 as shown in the attached graph.

#### Explanation:

solving for $x$ by making $x$ the subject of the equation:

$2 x + 9 < 16$
$2 x < 16 - 9$
$2 x < 7$
$x < \frac{7}{2}$ or $x < 3.5$

graph{x<3.5 [-10, 10, -5, 5]}

Plot the graph of x=3.5 with dotted line and shade the area of $x$ less then 3.5 as shown in the attached graph.
