Solutions of Linear Inequalities
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A linear inequality's solution is the set of every value that makes it true — typically an interval, not a single number.
Show
x + 3 < 7 is satisfied by 0, by 3.9, by −100 — the whole interval (−∞, 4), written in one stroke.
Watch for
Solving an inequality means naming the whole set.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
