Linear Inequalities
You've already seen linear equations like this: x - 2 = 0. You solve for x and get x = 2. Our variable, x, has a single value that we can determine. That's straightforward but also a little dry. It's like finding out that hot sauce is hot sauce and not comparing it to any potentially inferior condiments.
But then there are linear inequalities. A linear inequality is a linear expression that contains relational symbols. That means that instead of this (=), you'll see >, , or
