Inequalities are similar to equations, however, both sides are not equal.

We use variables to represent a variety of solutions to the inequalities.

> means greater than
< means less than

write a line underneath each to include equals to.

Tips about solving inequalities

You want to isolate the variable so you are solving for x (or whatever variable is chosen)

Remember when you DIVIDE or MULTIPLY by a negative number the sign FLIPS.

When graphing inequalities you use an open circle when the inequality uses < or >.

Use a closed circle when graphing an inequality that includes the equal sign.

Things to focus on:

- Solving equations with just variables for example solve for h in this equation... 4h=c+b

- Graphing inequalities and writing an inequality from a word problem.

- Solving multi-step equations
- Plugging in ordered pairs for inequalities and multi-variable equations.
