Identity, Conditional, and Inconsistent Equations
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Every linear equation is one of three kinds: an identity is true for all values, a conditional for some, an inconsistent for none.
Show
2(x + 1) = 2x + 2 holds for every x; 2x = 6 holds only at 3; x + 3 = x + 5 holds never.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
