1. Lesson 3.1
How do you solve one-step equations using subtraction, addition, division, and multiplication?
Solve one-step equations by using inverse operations to isolate the variable.
You add, subtract, multiply or divide the same number on each side.

2. Lesson 3.2 How do you solve two-step equations?
First look for like terms and combine them, then use inverse operations to isolate the variable when solving two-step equations.

3. Lesson 3.3 How do you solve multi-step equations?
First simplify and combine like terms. After simplifying, use inverse operations to isolate the variable.

4. Lesson 3.4 How do you solve equations with variables on both sides?
Simplify both sides, put variables one side, and then solve using inverse operations to isolate the variable.

5. Lesson 3.5 How do you find ratios and write and solve proportions?
A ratio is an expression that relates one quantity to another by division, while a proportion is an equation with two ratios.
Solve proportions with variables by using inverse operations to isolate the variable.

6. Lesson 3.6 How do you solve proportions using cross products?
Multiply the numerator of each ratio by the denominator of the other ratio, and write an equal sign between the two products.
Then solve for the variable.

7. Lesson 3.7 How do you solve percent problems?
To solve percent problems, use the percent equation or a proportion.
You will know two parts and have to find one.

8. Lesson 3.8 How do you rewrite equations?
To rewrite the equation so that y is a function of x, rewrite the equation so that y is isolated on one side of the equation.
For all literal equations, solve for the given variable by using properties of equality and inverse operations.
