Mathematics — first biennium · Lesson
A reduction can lead to one solution, a contradiction, or an identity. Do not automatically write x=0 when the unknown disappears: inspect the final equality.
In this lesson: Interpret the terminal form of an equation and distinguish one solution, no solution and infinitely many solution values.
You can already assume: Linear equations with complete simplification.
