Solving 2 Step Equations: Day 2 Challenge

This video tutorial covers the process of solving two-step equations using distribution. It begins with an introduction to key terms such as variables, constants, and coefficients. The instructor then explains the distributive property and demonstrates how to apply it to solve equations. Several example problems are solved step-by-step, highlighting the importance of distributing first before isolating the variable. The tutorial concludes with a reminder to practice these techniques in class.
