Using Elimination to Solve Systems

The video tutorial explains solving equations using elimination and substitution methods. It highlights that both methods require two operations: undoing addition/subtraction and multiplication/division. The elimination technique is detailed, showing how to multiply equations to eliminate variables. The tutorial also covers solving for variables and verifying solutions using alternative methods.
