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?

\n" ); document.write( "When checking solutions of equations and inequalities there are no significant differences. You just take a possible solution and substitute that number into the original equation/inequality to see if it works.

\n" ); document.write( "The only difference is that for equations there is a specific list of one or more solutions to check. When checking an inequality there are usually an infinite number of possible solutions. For example, if you get x < 4 as a solution, any number less than 4 (and there are an infinite number of numbers below 4) should work.

\n" ); document.write( "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?

\n" ); document.write( "Yes, but only if it is an \"or equal to\" type of inequality.
