Expressing Relationships as Algebraic Expressions

1. Expressing Relationships as Algebraic Expressions

Algebraic expressions, or mathematical sentences with numbers, variables, and operations, are used to express relationships. Learn how to solve algebraic expressions with various operations, such as addition and multiplication, and using multipe variables.

Practice Simplifying Algebraic Expressions

2. Practice Simplifying Algebraic Expressions

Algebraic expressions are simplified using two useful concepts: combining like terms and the distributive property. Learn how to use combining like terms and the distributive property to simplify algebraic expressions, and understand the solutions to the practice problems.

Problem-Solving using Linear Equations

3. Problem-Solving using Linear Equations

Word problems can be solved after being translated into linear equations. Learn what a linear equation is and how to use it to solve simple problems, and take a look at some real-world practice problems.

Solving Linear Equations: Practice Problems

4. Solving Linear Equations: Practice Problems

Linear equations are algebraic expressions of a line. Become familiar with recognizing and solving linear equations through examples and practice problems.

Solving Equations Using the Addition Principle

5. Solving Equations Using the Addition Principle

When solving equations using the addition principle, addition or subtraction done on one side of an equation must be done on the other side to remain the same. Learn more about this addition principle as well as three examples of it in practice.

Solving Equations Using the Multiplication Principle

6. Solving Equations Using the Multiplication Principle

When solving equations using the multiplication principle, multiplication or division must be done on both sides of the equation to stay the same. Learn more about this principle, including how to use it and some examples in multiplication and division.

How to Solve Equations with Multiple Steps

7. How to Solve Equations with Multiple Steps

Solving an algebraic equation can involve multiple steps of addition, subtraction, multiplication, and division to isolate the variable. Learn how to solve equations with multiple steps, and practice the correct order of the steps with examples.
