Question 317359
How do you know if a value is a solution for an inequality? 
<pre><b>
Substitute the value for the variable and see if it leads to a true inequality.
</pre></b>
How is this different from determining if a value is a solution to an equation? 
<pre><b>
It isn't. Substitute the value for the variable and see if it leads to a true equation.
</pre></b>
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?
<pre><b>
Yes, but only sometimes when the inequality sign is {{{"">=""}}} or {{{""<=""}}} but never when the inequality sign is {{{">"}}}, {{{"<"}}} or {{{""<>""}}}.
