How do you substitute an inequality in an equation? - Answers

To substitute an inequality in an equation, first identify the variable in the equation that you want to replace. Then, use the inequality to express that variable in terms of others, ensuring the substitution maintains the relationship dictated by the inequality. It’s important to remember that inequalities can change the nature of the solution set; for instance, if you substitute a variable with an inequality, the resulting equation may have a range of solutions rather than a single value. Finally, solve the equation as usual but consider the implications of the inequality in your final results.
