Solving Equations Using Properties and Justification

This video tutorial teaches how to solve equations by using properties to justify each step. It covers the symmetry property, additive inverse property, and multiplicative inverse property. The tutorial addresses common misunderstandings, such as forgetting the two sides of an equation, and demonstrates solving equations with steps, pictures, and justification. The use of visual aids helps in understanding the concept of opposites in equations.
