Subtraction Property of Inequality
The Subtraction Property of Inequality states that subtracting the same quantity from both sides of an inequality preserves the direction of the inequality. For any numbers , , and :
If , then
If , then
The same rule applies to and . This property is used to solve inequalities in which a number has been added to the variable. Subtracting that number from both sides isolates the variable while keeping the inequality symbol facing the same way. For example, to solve , subtracting from both sides yields , and the symbol is unchanged.
