When dealing with inequalities, there are a few common mistakes you should be careful to avoid. Here’s what you need to know:

1. Flipping Signs the Wrong Way: You should only flip the inequality sign when you multiply or divide by a negative number.
   For example, if you start with $-2x > 6$ and divide by $-2$, you have to flip the sign. It becomes $x < -3$.

2. Missing the Range of Solutions: It's important to show the right range of numbers on a number line.
   For example, if you have $x < 4$, make sure to show all the numbers that are less than 4.

3. Mixing Up Solutions with Equalities: Remember that inequalities don’t just have one answer.
   For instance, $x \geq 2$ means any number that is 2 or greater, like 2, 3, 4, and so on.

Be careful and watch out for these common mistakes!
