Question

what is an inequality?

Answer 1

An inequality is basicallya statement about the relative size or order of two objects. x>2, When you see that you know that x can be any number that is greater than 2.
basic inequalities in algebra are a lot like equations. ex.
7x>21
you can divide both sides by 7 to get x>3.
The difference is that if the inequality was -7x>21,
when you divide both sides by a negative number(in this case 7) greater than becomes less than, and vice versa. the answer to this would be x<-3
