🛎️ Systems of Linear Equations
- When x + y = 20 and x − y = 10 form a system, they are solved together.
- We look for x and y values that make both equations true at the same time.
🛎️ Solving a System Graphically
- Rearrange both equations into y = mx + c form.
- Plot both lines and find where they intersect.
- The point of intersection is the solution of the system.
🛎️ Solutions of a Linear System
- There is one solution if the lines intersect once.
- There is no solution if the lines are parallel.
- There are infinite solutions if the lines overlap exactly.
