How do you know if a value is a solution for an inequality?

How do you know if a value is a solution for an inequality?


How is this different from determining if a value is a solution to an equation? If you replace the


equal sign of an equation with an inequality sign, is there ever a time when the same value will be


a solution to both the equation and the inequality? Write an inequality and provide a value that


may or may not be a solution to the inequality.How do you know if a value is a solution for an inequality?
HI,


suppose tthe inequality is x %26gt; 2, and thus its equation is x = 2


therefore for such inequality values the solution is anything above 2 i.e. 2.1, 2.2, 3, 6 , 99 etc but for the equation there is only one solution and that is 2. and in this case the solutions are different.


No there can never be a time when the solution of inequality has the same value of that of the equation. this is because, equations generally have one or two or theree or atleast finite solutions but inequalities have infinite solutions.


Now again for the inequality x%26gt;2, 2 is not its solution but 2.2 is. Hope to answer you well. keep smiling. bye.
