INTRO
An inequality is a math sentence that uses an inequality symbol () to tell us how two values or expressions compare to one another.
The inequality below reads is less than .
If we imagine the numbers on a number line, we can see that is less than because it is farther to the left.
If we divide (or multiply) an inequality by a negative number, we need to flip the inequality sign to make the inequality true again.

We can imagine dividing (or multiplying) by a negative as flipping the points on a number line. When we do this, we can see that is farther to the right than ; therefore, the inequality becomes is greater than than .
KEY STEPS

## How to Solve Linear Inequalities

### Step 1. Move all the terms with the unknown variable to one side of the equation.

Use the same inverse operations on both sides to do this.

### Step 2. Move all the terms with known values or variables to the other side of the equation.

Use the same inverse operation on both sides.

### Step 3. Isolate the unknown variable.

Since division is the inverse operation of multiplication, we divide both sides by the number the variable is multiplied by.
If we divide by a negative number, we need to flip the inequality symbol.
