In this lesson, viewers are taught how to solve systems of equations using elimination with addition and subtraction. The elimination method involves canceling out either the X or Y variable by adding or subtracting depending on the situation. The goal is to ensure that either the X terms or the Y terms have the same coefficient. The lesson covers different scenarios and provides step-by-step examples to help students understand the concept.
