document.write( "Question 222429: 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 and put an inequality sign in its place, is there ever a time when the same value will be a solution to both the equation and inequality? \n" ); document.write( "

\n" ); document.write( "\n" ); document.write( "If you replace an inequality sign with an equals sign, there is one possible situation where a value will satisfy both the equation and the inequality. That is the situation where the inequality sign is inclusive of equals, i.e.

. In this case, any element of the solution set of the equation is an element of the solution set of the inequality.\r
