Inequalities are expressions which indicate when a variable is:
|<||is less than, so 2 < 5 is a true statement|
|>||is more than, so 6 > 4 is a true statement|
|is less than or equal to, so 2 5 is true and so is 2 2.|
|is more than or equal to, so 6 4 is true and so is 6 6.|
An expression such as is similar to the equation . However, this time we are looking for numbers which if you multiply by 3, then subtract 7, you get an answer of less than 8.
Unlike , which has just one answer, there are lots of numbers for which this is true (in fact, an infinite number). So our answer is not a number, but a range of numbers.
Solve inequations just like equations: what you do to one side, you must do to the other.
