An inequality is a mathematical sentence that states that one quantity is less than (or greater than) another quantity. SOL 7.22. A one-step equation is defined as an equation that requires the use of one operation to solve (e.g., x + 3 = –4). A one-step inequality is defined as an inequality that requires the use one operation to solve (e.g.,

For 3x – 5 = 16, the only solution is x = 7. When we have an inequality to solve (greater than, less than, greater than or equal to, or less than or equal to) we have a range of numbers that can be a solution. In that range there is an infinite amount of possible numbers that make the inequality true. Example: x > 3 We know 4 is greater than 3.

For example, 3x – 2 < 7 is a linear inequality. We call it “linear” because if the < were replaced with an = sign, it would be a linear equation. Inequalities involving polynomials of degree 2 or more, like 2x3 – x > 0, are referred to as polynomial inequalities, or quadratic inequalities if the degree is exactly 2.
