This lesson explores systems of equations, focusing on what they share with their sum. It covers the definition of a system of equations, provides an example, and explains how solutions are found. The lesson discusses the effects of multiplying and adding equations, showing that adding equations creates a new system with the same solution. Graphical representations and intersections are examined, emphasizing that the solution remains consistent. The lesson concludes by reinforcing the concept that adding equations results in a new system with the same solution point.

How do the tables of values and graphs help in understanding systems of equations?

What is the relationship between the original equations and the new equation created by adding them?
