What you'll learn
- Solve a system of two linear equations by substitution or by elimination (including when scaling is required), choosing the method from the system's structure
- Identify a solution to a system as an ordered pair satisfying both equations, the intersection point of the two lines
- Answer a question that asks for a combination of the variables, such as `x + y`, obtaining it directly from the equations when their structure allows
