Linear equation - identity, contradiction, and conditional equation
Показать описание
This video demonstrates the various special solutions to linear equations:
Identity - x is completely eliminated on both sides and the two sides are equal
Contradiction - x is completely eliminated on both sides and the two sides are unequal
Conditional equation - the traditional algebra equation with a solution with x on one side of the equals and a number on the other side.
