# Expressions, equations, & inequalities

Contents

Bring on the algebra! Learn how to manipulate expressions and solve equations and inequalities.

Learn how to combine like terms (with negative numbers and variables), including more complex problems involving the distributive property.

Learn how to factor and expand algebraic expressions (expressions with variables) by applying the distributive property.

Any expression (mathematical or otherwise) has meaning. Help us match the linear expression to the meaning options given. In some cases, more than one meaning may apply.

Learn how to solve equations like 2x+7=13 and 3(x+4)=3, which can be solved in two steps.

Get some practice solving two-step equations that involve decimals and fractions

Learn how to set up and solve equations to find answers to real-world questions.

Learn how to solve (mathematical) inequalities. A key concept in this tutorial is flipping the inequality sign when multiplying or dividing both sides by a negative number.

Learn how to solve more complex (mathematical) inequalities. Also learn to construct inequalities to model real-world situations.
