Solving Systems of Equations
- 6 Order System: The correct terminology for addressing a system comprising six variables is "Solving a 6 order system."
- Solution Set Types:
- Systems can lead to three types of solution sets: empty set, one solution, or infinite solutions.
Specific Systems and Their Solutions
- Equations x + y = 4 and x - y = 0: This system has one solution.
- Equations x - y = 5 and 2x + y = 1: This system also results in one solution.
- Equations x + y = 5 and x + y = 7: These equations contradict each other, leading to an empty set of solutions.
- Equations 3x + 2y = 6 and x - y = 2: This system yields one solution.
Infinite Solutions
- Equations 2x - y = 7 and 2y = 4x - 14: Represent a scenario with infinite solutions, indicating dependent equations.
Identifying Solutions from Given Points
- System of Equations (4x + y = 1, y = x + 6): The point (-1, 5) satisfies this system.
- System of Equations (y - x = -1, x + y = -5): The point (-2, -3) is a valid solution.
Summary
- Understanding how to classify solutions is crucial for analyzing systems of equations.
- Identifying solutions from proposed points requires substitution into the equations.
