# How do you solve 2x - 1 < 9?

Solve for $x$ just like we do when there is an equals sign to get $x < 5$

#### Explanation:

First we need to solve for $x$, just like we do when there is an equals sign by adding 1 to both sides:

$2 x - 1 < 9$
$2 x < 10$

Let's divide by 2:

$x < 5$

And that's the answer. Keep in mind that if you multiply or divide by a negative number, the "fish mouth" will change direction! We didn't in this example but in future questions I'm sure you'll face that possibility.
