How Solve a System of Equations Using Elimination

The video tutorial explains the method of elimination by subtraction in solving equations. It emphasizes the importance of having the same coefficient and sign for variables to effectively use this method. The instructor compares subtraction with addition, showing how both can be used to eliminate variables, but focuses on subtraction as requested. The process of solving for variables X and Y is demonstrated, highlighting the flexibility of plugging values back into equations to find solutions. The tutorial aims to clarify the steps and logic behind using elimination methods in algebra.
