Which is an inequality?

An inequality is a mathematical statement that indicates one quantity is less than, greater than, less than or equal to, or greater than or equal to another quantity. For example, the expression ( x < 5 ) is an inequality, meaning that ( x ) is less than 5. Other examples include ( 3y + 2 \geq 10 ) and ( a - b \leq 0 ). Unlike equations, inequalities do not assert equality but rather a relationship of order between values.
