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? Write an inequality and provide a value that may or may not be a solution to the inequality.

Karine,
An inequality shows two statements that are true only if one statement differs from the other by being greater than, or equal to the other. ex: x+1>3 changing > to = then x will be x=2 now substitute the > gives you x>2. Inequalities have multiple solutions, while equations have a unique solution. If the solution is the solution of an inequality, it will not be a solution of the equation formed from the inequality unless the inequality has a greater than, or equal to sign or a less than or equal to sign in that case x=the same value that x>= and that value is the unique solution to the equation formed from the inequality.
20+14>34 20+n>34 makes it a false statement
20+14=34 therefore 34=34 true
20+n>34
20+15>34 true
35>34 true
20+15=34 false
Hope this helps you understand it better
