## Description

Elayn Martin-Gay firmly believes that every student can succeed, and her developmental math textbooks and video resources are motivated by this belief. **Algebra: A Combined Approach****, Fourth Edition** was written to provide students with a solid foundation in algebra and help them effectively transition to their next mathematics course. The new edition offers new resources like the **Student Organizer** and now includes **Student Resources** in the back of the book to help students on their quest for success.
