How is inequality different from an equation? give a real world scenario in which you would write an inequality rather than an equation

An inequality uses less than, greater than, greater than or equal to, and less than or equal to. Where an equation uses an equal sign and sometimes a variable. If you could only spend a certain amount of money or less you would use an inequality because it would be x is equal to or less than 10, it would not work with an equation.

3x+9+4x+x=8x+9that's the answer for your question.
