Linear Inequalities

≤

The ≤ symbol means less than or equal to, including both the values less than and equal to a number.

0, 1, 2, 3, 4, 5, 6

These are the values of x that make 30x less than 200, as demonstrated in the chapter's example.

Equal numbers can be added to or subtracted from both sides without changing the sign

This rule allows manipulation of inequalities while maintaining the original relationship.

Linear inequality in one variable

It's a linear inequality because it involves a single variable to the first power.
