Question

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.

Answer 1

One can substitute the value back in to the inequality to see if the inequality is true. This can be done in equations also.
