How to Find the Solution to a System by Using Elimination

The video tutorial explains solving equations using substitution and elimination methods. It begins with substitution, where one variable is solved and plugged into another equation. The tutorial then introduces the elimination process, focusing on identifying coefficients and using subtraction to eliminate variables. After eliminating a variable, the tutorial demonstrates solving for the remaining variable and using substitution to find the other variable. The video concludes with writing the solution as a coordinate point.
