# Solving inequalities

This course is a part of
**Algebra I**, a 17-course Topic series from Khan Academy.

Learn how to solve linear inequalities with a single variable. For example, solve -3(x+1)>2x-7. Learn how to solve compound inequalities. For example, solve 2x+1>3 AND -x-5<4.

This course contains 5 segments:

**Introduction to inequalities with variables**

Algebraic inequalities (inequalities with variables) are useful for describing real-world situations. Learn how to write inequalities and graph them on the number line.

**One-step inequalities**

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.

**Two-step inequalities**

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

**Multi-step inequalities**

Solve any possible linear inequality in one variable. For example, solve -3x-7

**Compound inequalities**

Learn how to solve compound inequalities. For example, solve 2x+1>3 AND -x-5<4.
