Simultaneous Equations with No Solutions or an Infinite Number of Solutions - Full Lesson

We learn about Simultaneous Equations with No Solutions or an Infinite Number of Solutions (full lesson). If there are no solutions then we'll be faced with a mathematical contradiction. If there's an infinite number of solutions then we'll be faced with the result 0=0 or k=k.
Here we work through 2, detailed, examples in which we'll develop a solid understanding of these two scenarios.
